Myself and some friends are taking part in a weight loss challenge this year and I will be recording monthly weigh in's and body measurements. I need to find a calculation which will work out the difference's in inches and pounds.
I have the item title in column B from row 10 down to Row 17. The first one in Row 10 is weight which is calculated in pounds.
Then going across from Column C is the month starting with Jan ending in December in Column N.
The total loss needs to be updated after every monthly entry into column O.
Unfortunately I cannot post a picture of the table as I'm new to this group.
I've tried other formulaes suggested to people with similar problems but they don't work for me.
Can anyone help?
Many Thanks
Helen
Bit hard to work it out from your description but I think you are looking for
=C10-MIN(D10:N10)
That assumes the largest figure will always be in column C and will update every time a new entry is placed in the row.
If the weight might go up (not that you are going to fail the challenge) you could use
=C10 - LOOKUP(1,1/(D10:N10<>""),D10:N10)
This should do the trick. (And you can copy down to other rows as necessary)
=INDEX(C10:N10,1,COUNT(C10:N10))-C10
INDEX used here, returns the value from the range C10:N10 in the first and only row, where the column is determined by the count of values already entered. So if you have values entered for 4 months, the formula will take April's value and subtract January's value.
A negative number will represent weight loss. A positive number means weight gain.
Total fat loss :
(AVERAGE(C10:N10) - C10)*2

I have a sheet which calculates the Peak Equity (CS) as well as the Total Equity (CR); both of these eventually wind up being different at some point, as one is calculating from the peak, whilst the other is just the current total.
The difficulty always comes with anything like this when autofiltering, so I need some assistance
I have a formula (two actually) which works well on Total Equity (CR), even when the sheet is autofiltered.
Both =10000+SUBTOTAL(109,CR$18:CR18) and =AGGREGATE(9,7,CR$18:CR18)+10000 do the job perfectly. I have used the SUBTOTAL one in this sheet
To calculate the Peak Equity (CS), requires finding the maximum of either the previous Peak Equity (CS) or current Total Equity (CR). The first row (CS18) is not able to use the same formula as there is no previous data row, so in this cell (CS18), I used the starting bank in the calculation instead.
Assuming the first row of data is 18, the basic formula in column CS is =MAX(CR19,CS18). This formula works fine when the sheet is not filtered, but falls over when it is autofiltered, for obvious reasons. Is there a way to have column CS be dynamic, always showing the correct Peak Equity?
As an afterthought, could the starting bank be possibly part of the formula to help resolve the issue? I'm just not sure how to address this issue. It doesn't matter what that bank is, but let's just use 10000 as a starting point for now if that helps.
Some additional explanation is needed so hopefully I can make what clearer
The first 17 rows are taken up with performance statistics. After that:
Profit or Loss is column N,
Current Bank is column CR,
Bank Highest Position (Peak) is CS
CR is the current total of what is visible in N - =10000+SUBTOTAL(109,N$18:N18)
CS needs to always be the larger of CR of the current row and CS of the previous row, but how is that possible in the first visible row as there is no previous row to use?
As the first 17 rows are taken up with data showing strike rates etc, whatever row is in position 18 will basically need to fulfil this =N18+10000 with 10000 being the starting bank
A couple of provisos change things a little, though, as CS can never be below the starting bank figure, let's assume 10000, so if the first row of N was a loss, CS would still be 10000, if that makes sense. As profit grows, CS also grows, but it can never go backwards, as it is always the peak. CR is simply the current $ amount in the bank. CS is the high point and will always be greater or equal to CR..
So I'll try it in English. CS would be something like this
IF current row is the first row, then the higher of N + 10000, or 10000. IF not the first row, then the higher of 10000, CR of current row or CS of row above.
I hope this helps a little bit, as I am not sure how to express this in a formula which will work when filtered
Thanks so much in advance
Regarding the starting bank value, how about wrapping the peak equity function inside IFERROR, like so:
IFERROR( function , starting bank value or cell reference)
I am working on a model of charging load of electric vehicle. I am attaching a link to an excel workbook for your better understanding.
Column B contains random time values
Column G to P represents houses and each house can have 1 car. So the each time values needs to be distributed in one column. Now when a car is plugged in, its load stays constant for 3 cells.
I want excel to randomly distribute these cars e.g. 4 cars to 4 houses and leave others blank.
what i can think of is, to assign each time a random house then use IF formula with AND function to match random times with time series and second condition to match random houses with columns 1-10.
the problem i am facing is, the formula gives a value error and only works in the rows with has random generated time in front of them screenshot. I know there is a very small thing that i am missing. please help me find it
Regards
workbook
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(AND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))>=$F6,INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))<=$F6+TIME(0,30,0)),11,""))
The two elements in the AND find the house number in column C and return the corresponding time in column B.
The first element compares the time in F to that time. The second element compares the time + 30 minutes to F (three cells). If it's between those two times, it gets an 11.
The ISNA makes sure that the house in question is on the list. You could also use an IFERROR, but I prefer the precision of ISNA.
Update
If you want the values to wrap around, you need to OR compare to the next day.
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(OR(AND(ROUND($F6,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,30,0),5)),AND(ROUND($F6+1,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6+1,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,30,0),5))),11,""))
That formula structure looks like
=If(isna(),"",if(or(and(today,today),and(tomorrow,tomorrow)),11,"")
This formulas already getting too big. If you triple it for your three voltages, it will be huge. You should consider writing a UDF in VBA. It won't be as quick to calculate, but will probably be more maintainable.
If you want to stick with a formula, you could put the wattage in row 4 above the house number. Then in another table, list the wattages and minutes to charge. So in, say, B12:C14 you have
3.7 120
11 30
22 15
Now where you have 11 in your formula, you'd have G$4 and the two placed you have TIME(0,30,0), you'd have TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0). I re-arranged some stuff to make it more 'readable' (but it's still pretty tough) and here's the final formula
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(OR(AND(ROUND($F6,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0),5)),AND(ROUND($F6+1,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6+1,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0),5))),G$4,""))
I am new to Spotfire and need help in getting the right expression for a calculated column.
My Data contains different subjects grouped in column ID. For every ID, Bodyweight was measured on different days. Days are given in column Day and stated as 1,2,3...
The last day is denoted by Last and Bodyweight measurements given in another column. Another column is present which is called Baseline. The Body weight measured is considered as baseline if the column contains a Y for that row.
I need to insert a calculated column, which will contain the difference between Body measurement measured on Day denoted Last and Body measurement marked by Y in column Baseline.
This should be done for every new ID. I am not able to figure this out. Could someone advise me on how to go about it?
Here is an example attached
So, the calculated column for Rita will give -4 (body weight at Last=56 and BodyWeight at baseline=56, so 52-56 =-4)
the sample data you provided is a little weird, particularly the [Day] column. if it's within your control, I suggest to use actual dates rather than a number/string here.
barring that, I was able to get your desired results, but it required two calculated columns: the first one will consolidate the [Day] and [Baseline] columns into a single column, and the second one contains your desired info.
column 1, which I called Day (int):
CASE
WHEN [Day]="Last" THEN 1000000
WHEN [Baseline]="Y" THEN -1000000
WHEN [Day]!="Last" THEN Integer([Day])
END
I picked a random high and low max to establish a chronological order. this will put 1000000 in place of "Last" (if you have any programs that are longer than one million days, you'll need to increase this number). the same for the [Baseline] column, but that value will be -1000000, which is presumably the lowest value you will ever see in this column. both of these are assumptions and may not work for your implementation. finally, in all other cases, the day number will be used.
column 2, which I called Diff:
Last([Weight]) OVER (Intersect([Name],LastNode([Day (int)]))) -
First([Weight]) OVER (Intersect([Name],FirstNode([Day (int)])))
the first line uses what's called an OVER expression to retrieve the first value for [Weight], ordered by [Day (int)], per [Name]. the second line gives the reverse of that, and so the difference is calculated as -4 (or whatever is appropriate).
Say I have the dataset below, what is the most efficient formula to fill the cells in column D, where the number of patients alive are calculated?
Example data set in excel
The way it should calculate is:
month 1: 8*100% = 8
Month 2: 8*80%+6*100% = 12.4
Month 3: 8*75%+6*80%+9*100% = 19.8
...
Month 10: etc.
The problem that I have is that which each row, the formula becomes longer. It is feasible to just manually enter the formulas for small datasets, but as datasets become larger, this task becomes unfeasible.
I have been able to use VBA to code the survival of the number of new patients column (C). But then I would have to rerun the VBA code as soon as I change a single value in that column.
I have a feeling it should be possible with some combination of the INDEX function in excel, I just haven't been able to figure it out.
Who can help me out here?
Kind regards,
Sander
If moving the data a bit is allowed at least for the calculation, you could do something like this:
=SUMPRODUCT($F$11:$F$20,B2:B11)
It uses a reversed list of your current list of new patients. That list is created with (formula obtained from this site):
=INDEX($C$11:$C$20,COUNTA($C$11:$C$20)+ROW($C$11:$C$20)-ROW())
Result:
The added space is necessary for the formula to work (so that it gets 0% for patients not present yet).
Or one where you don't have to leave spaces (everything from above is reversed however):
=SUMPRODUCT($C$2:$C$11,G11:G20)
I'm trying to perform an AVERAGEIFS formula on some data, but there are 2 possible results and as far as I can tell AVERAGEIFS doesn't deal with that situation.
I basically want to have an ELSE inside it.
At the moment I have 2 ranges of data:
The first column only contains values 'M-T' and 'F' (Mon-Thurs and Fri).
The second column contains a time.
The times on the rows with an 'F' value in column 1 are an hour behind the rest.
I want to take an average of all the times, adjusting for the hour delay on Fridays.
So for example I want it to take an average of all the times, but subtract 1 hour from the values which are in a row with an 'F' value in it.
The way I've been doing it so far is by having 2 separate results for each day, then averaging them again for a final one:
=AVERAGEIFS(G3:G172, B3:B172, "M-T")
=AVERAGEIFS(G3:G172, B3:B172, "F")
I want to combine this into just one result.
The closest I can get is the following:
=AVERAGE(IF(B3:B172="M-T",G3:G172,((G3:G172)-1/24)))
But this doesn't produce the correct result.
Any advice?
Try this
=(SUMPRODUCT(G3:G172)-(COUNTIF(B3:B172,"=F")/24))/COUNTIF(B3:B172,"<>""""")
EDIT
Explaining various steps in the formula as per sample data in the snapshot.
SUMPRODUCT(G3:G17) sums up all the value from G3 to G17. It gives a
value of 4.635416667. This after formatting to [h]:mm gives a value
of 111.15
OP desires that Friday time be one hour less. So I have kept one hour less for Friday's in the sample data. Similar SUMPRODUCT on H3:H17 leads to a value of 4.510416667. This after formatting to [h]:mm gives a value
of 108.15. Which is exactly three hours less for three occurrences of Fridays in the sample data.
=COUNTIF(B3:B17,"=F") counts the occurrences of Friday's in the B3:B17 range which are 3 occurrences.Hence 3 hours have to less. These hours are to be represented in terms of 24 hours hence the Function COUNTIF() value is divided by 24. This gives 0.125. Same is the difference of 4.635416667 and 4.510416667 i.e. 0.125
Demonstration column H is for illustrative purposes only. Infact Friday accounted values that is 108.15 in sample data has to be divided by total data points to get the AVERAGE. The occurrences of data points are calculated by =COUNTIF(B3:B17,"<>""""") with a check for empty columns.
Thus 108:15 divided by 15 data points give 7:13 in the answer.
Revised EDIT Based upon suggestions by #Tom Sharpe
#TomSharpe has been kind enough to point the shortcomings in the method proposed by me. COUNTIF(B3:B172,"<>""""") gives too many values and is not advised. Instead of it COUNTA(B3:B172) or COUNT(G3:G172) are preferable. Better Formula to get AVERAGE as per his suggestion gives very accurate results and is revised to:
=AVERAGE(IF(B3:B172="M-T",G3:G172,((G3:G172)-1/24)))
This is an Array Formula. It has to be entered with CSE and further cell to be formatted as time.
If your column of M-T and F is named Day and your column of times is named TIME then:
=SUMPRODUCT(((Day="M-T")*TIME + (Day="F")*(TIME-1/24)))/COUNT(TIME)
One simple solution would be to create a separate column that maps the time column and performs the adjustment there. Then average this new column.
Is that an option?
Ended up just combining the two averageifs. No idea why I didn't just do that from the start:
=((AVERAGEIFS(G$3:G171, $B$3:$B171, "F")-1/24)+AVERAGEIFS(G$3:G171, $B$3:$B171, "M-T"))/2
