I am trying to fill a column in Excel with values that are generated randomly but the sum of all the values total to the end.
Example:
Starting value = 320
Final value = 350
Need to generate 2 more values which have random difference between them but total to 350 at the end, as in: 2nd val = 12, 3rd val = 18.
The script/formula should generate different values when run next (for another table etc.). It may generate, for the same starting and final values, 15 and 15 or 8 and 22 for the 2nd and 3rd values respectively etc.
Basically what the formula should do is: Find the difference between the starting and final values then randomly add a number to create the 2nd entry. Now the third entry should follow the same pattern but the value generated should end up totaling to the final.
The example is only for 2 values but I'm working on tables ranging from 15-30+ values.
I don't know if Excel can do it, or if there's a mathematical formula that will work here.
Thanks in advance for all the help!
You need something like this:
That gives:
The trick is to generate a list of uniform random numbers between 0 and 1 and then scale those numbers up the total that you're looking for.
I was doing R&D on Excel. And wanted to use If-else ladder in column of excel.
Let's say I have a 2 columns and I calculated the difference between the two columns. Now, If the difference is between a range of (-5 to +5), if should display something or if Difference greater than 5, it should display something and for rest i.e. difference < -5, should display something else.
I tried and came up with this
=IF("H2>5",<something1>, IF("H2<5",<something2>))
How to put the range part in this if-else ladder? Also the above If else is not giving value but the result is turning out to be #VALUE.
Thanks for your help.
Try
=IF(H2<-5,"Negative",IF(H2<=5,"In Range","Positive"))
There could be 3 possibilities only, 1 the answer is between -5 to 5 inculdining -5 and 5. 2 greater then 5. 3 smaller than -5. so this should work
=IF(AND(H2>=-5,H2<=5),"between -5 &5",IF(H2<-5,"Smaller than-5",IF(H2>5,"greater than 5 ")))
let me know if this is what is required.
How can I return the ranking of each value in a row, even in the case of duplicates? Please see my example below.
While many questions have been answered regarding the handling of duplicate values in a ranking, I have come short in achieving a method that works for all of my cases.
EDIT: The previous picture above was a bad example that did not address my problem. Here is a new picture of the behavior.
In certain cases it skips to 7 when the rank should only be 1:6. In other cases it seems to work, and then not work in similar cases. Data is:

EDIT2: Implementing RANK instead of RANK.EQ showing no difference:
I think you've got an error in your setup. My understanding is each row is meant to be a separate independent case, however your formula for calculating rank has fixed row and column references, when it should have only fixed column references. Right now, the rank for every value is being found based on the first row in your data. Instead of:
=RANK.EQ(B4,$B$4:$G$4,1)
It should be:
=RANK.EQ(B4,$B4:$G4,1)
This then alters your results in the 2nd and 3rd blocks and you should get the desired result in the 3rd block.
With the formula below in Cell B2:B4 you can filter the unique numbers in Column A.
Please note that this is an array formula so once you enter it you have to mark it and press CTRL + ALT + DEL. Hope this solves your problem. More details regarding this formula you can also find here https://exceljet.net/formula/extract-unique-items-from-a-list

Try RANK instead of RANK.EQ as below. Though I am not sure whether this will work as I am testing on Excel 07.
Enter the following formula in Cell H1
=RANK(A1,$A1:$F1,1)+COUNTIF($A1:A1,A1)-1
Copy/Drag the formula down and across (to right) as required. See image for reference.
As per Microsoft Documentation on RANK.EQ function here
RANK.EQ gives duplicate numbers the same rank. However, the presence of duplicate numbers affects the ranks of subsequent numbers. For example, in a list of integers sorted in ascending order, if the number 10 appears twice and has a rank of 5, then 11 would have a rank of 7 (no number would have a rank of 6)
I'm new here, and I thought I would ask a question that certainly isn't found in the Microsoft Help Center and that I haven't been able to find a solution to either.
I am trying to calculate probability on things, and for the most part, Excel is very helpful in it. I'm running into problems though as I add additional variables.
My sheet currently is comparing dice rolls of 4 8-sided dice. 2 dice have certain symbols and the two other dice have different symbols. Some symbols negate each other, and in the end I come to a damage output number. When comparing 2 or 3 dice, the possible combinations are limited. 3 dice having 512 possibilities. With 4 now, there are 4096 possibilities and it's only going to get higher. This is why I need what I'm asking for.
Is there a way for a cell to understand is current position in reference to the block of cells it's currently in?
For example: I'm calculating a reroll possibility, but it will only happen half the time, meaning there are 12 possibilities of a single die with reroll option. So the current possibility table I'm developing is going to be 96 separate tables of 96 possible outcomes each. Table 1/1 is going to compare the first row of the 2 dice Attack roll table vs. the first row of the 2 dice Defense roll table. Row 1 Column 1 of this table is going to give the outcome of R1C1 of Attack table vs. R1C1 of Defense table. R1C2 of the table is going to give the outcome of R1C1 of Attack table vs. R1C2 of Defense table. R2C1 of this table will give the outcome of R1C2 of Attack table vs. R1C1 of Defense table, etc...
I know how to do the referencing to the tables, so I've made it so once I build one table, I can copy and paste it to build the other 96. But as I compare more dice rolls, this will quickly become too cumbersome to handle. If there is a way for a cell to understand where it's relative position is in a given block of cells (i.e. R2C1 of my example table understands that it is R2C1), it would cut down on my load immensely, and allow for me to continue building these probability tables so o can better understand tradeoffs in certain areas.
Any help is greatly appreciated.
Here's an Excel UDF I wrote for basic dice calculation %. It may not work directly for your example with negative/conditional outcomes, but it does have flexibility for testing more than one dice and the number of sides dice, so it might inspire you with some ideas. As previous comments suggested, if you gave exact parameters, you could probably get a specific example. My example returns a %. It currently only measures the probability of a single outcome, but you could do more than one formula per cell =DiceRollOdds(3,2)+DiceRollOdds(4,2) (to measure the probability of 3 and 4), or you can modify the code get something more specific.
Function DiceRollOdds(OutcomeToCheck As Integer, NumberOfDice As Integer, Optional SidesOnDice As Integer) As Double
Dim SuccessResult As Integer, FailedResult As Integer, SingleDice As Integer, RollResult As Integer
If SidesOnDice = 0 Then
SidesOnDice = 6
End If
Dim Rolls As Integer
For Rolls = 1 To (SidesOnDice ^ NumberOfDice)
RollResult = 0
For SingleDice = 0 To NumberOfDice - 1
RollResult = Int(Rolls / SidesOnDice ^ SingleDice) Mod SidesOnDice + 1 + RollResult
Next SingleDice
If RollResult = OutcomeToCheck Then
SuccessResult = SuccessResult + 1
Else
FailedResult = FailedResult + 1
End If
Next Rolls
DiceRollOdds = SuccessResult / (FailedResult + SuccessResult)
End Function
I need to be able to search my whole table for a row that matches multiple criteria. We use a program that outputs data in the form of a .csv file. It has rows that separate sets of data, each of these headers don't have any columns that are unique in of them self but if i searched the table for multiple values i should be able to pinpoint each header row. I know i can use Application.WorksheetFunction.Match to return a row on a single criteria but i need to search on two three or four criteria.
In pseudo-code it would be something like this:
Return row number were column A = bill & column B = Woods & column C = some other data
We need to work with arrays:
There are 2 kinds of arrays:
numeric {1,0,1,1,1,0,0,1}
boolean {TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}
to convert between them we can use:
MATCH function
MATCH(1,{1,0,1,1,1,0,0,1},0) -> will result {TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}
simple multiplication
{TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}*{TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE} -> will result {1,0,1,1,1,0,0,1}
you can can check an array in the match function, entering it like in the picture below, be warned that MATCH function WILL TREAT AN ARRAY AS AN "OR" FUNCTION (one match will result in true
ie:
MATCH(1,{1,0,1,1,1,0,0,1},0)=TRUE
, YOU MUST CTR+SHIFT+ENTER !!! FOR IT TO GIVE AN ARRAY BACK!!!
in the example below i show that i want to sum the hours of all the employees except the admin per case
we have 2 options, the long simple way, the complicated fast way:
long simple way
D2=SUMPRODUCT(C2:C9,(A2=A2:A9)*("admin"<>B2:B9)) <<- SUMPRODUCT makes a multiplication
basically A1={2,3,11,3,2,4,5,6}*{0,1,1,0,0,0,0,0} (IT MUST BE A NUMERIC ARRAY TO THE RIGHT IN SUMPRODUCT!!!)
ie: A1=2*0+3*1+11*1+3*0+2*0+4*0+5*0+6*0
this causes a problem because if you drag the cell to autocomplete the rest of the cells, it will edit the lower and higher values of
ie: D9=SUMPRODUCT(C9:C16,(A9=A9:A16)*("admin"<>B9:B16)), which is out of bounds
same as the above if you have a table and want to view the results in a diferent order
the fast complicated way
D3=SUMPRODUCT(INDIRECT("c2:c9"),(A3=INDIRECT("a2:a9"))*("admin"<>INDIRECT("b2:b9")))
it's the same, except that INDIRECT was used on the cells that we want not be modified when autocompleting or table reorderings
be warned that INDIRECT sometimes give VOLATILE ERROR,i recommend not using it on a single cell or using it only once in an array
f* c* i cant post pictures :(
table is:
case emplyee hours totalHoursPerCaseWithoutAdmin
1 admin 2 14
1 him 3 14
1 her 11 14
2 him 3 5
2 her 2 5
3 you 4 10
3 admin 5 10
3 her 6 10
and for the functions to check the arrays, open the insert function button (it looks like and fx) then doubleclick MATCH and then if you enter inside the Lookup_array a value like
A2=A2:A9 for our example it will give {TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE,FALSE} that is because only the first 3 lines are from case=1
Something like this?
Assuming that you data in in A1:C20
I am looking for "Bill" in A, "Woods" in B and "some other data" in C
Change as applicable
=IF(INDEX(A1:A20,MATCH("Bill",A1:A20,0),1)="Bill",IF(INDEX(B1:B20,MATCH("Woods",B1:B20,0),1)="Woods",IF(INDEX(C1:C20,MATCH("some other data",C1:C20,0),1)="some other data",MATCH("Bill",A1:A20,0),"Not Found")))
SNAPSHOT
I would use this array* formula (for three criteria):
=MATCH(1,((Range1=Criterion1)*(Range2=Criterion2)*(Range3=Criterion3)),0)
*commit with Ctrl+Shift+Enter
