it's been a while since I coded much in VBA so getting myself tangled in the loops.
I have a table (B3:E14) which I want to loop through to return all permutations, placing them one by one in the final column ("Test"), where I'll run some other code, then transpose that test column into a row of results with variables as columns.
Variable
Min
Max
Test
Apples
5
6
i
Bananas
2.5
3.5
j
Oranges
-2
-1
k
Does that make sense?
So my final table might look something like...
Run
Apples
Bananas
Oranges
etc
1
5
2.5
-2
2
6
2.5
-2
3
5
3.5
-2
4
5
2.5
-1
etc
2048
6
3.5
-1

Yes, it is possible to do that.

I'm trying to use Excle's SUMIF to calculate totals of Col1 to Col5 for dates that are similar.
My formula is as follows =SUMIF($A2:$A7,A10,$B2:$F7), but this only gives me the total of a single column.
How can I get the Totals of all the columns based on the date like I've shown in my results.
Date Col 1 Col 2 Col 3 Col 4 Col 5
1/5/2017 1 2 2
1/5/2017 5 3 1
1/5/2017 9 5 5
2/5/2017 10 5 3
2/5/2017 20 10 3
2/5/2017 6 8 1 5
Desired Results
1/5/2017 15 7 7 3 1
2/5/2017 30 11 11 11 8
use below formula in cell B11
=SUMIF($A$2:$A$7,$A11,B$2:B$7)
Per the example you provided, One solution is to use SUMPRODUCT
Multiplies corresponding components in the given arrays, and returns the sum of those products
Microsoft Docs give a thorough example, but per SO etiquette, here is an example in case of link-rot: [FYI, I used absolute reference for easier filling across, arbitrary how you get it done though]
Forumlas shown:
Formula is kind of hard to see without clicking on image:
=SUMPRODUCT(($B$3:$B$8=$B$11)*C3:C8)
This basically breaks down like this, it searches the B:B column for a match, and it will naturally return a true or false for the match, or 0/1 counterparts, and multiplys that by the number found in the column to the right (C3:C8), so it will either be 1 * # = # or 0 * # = 0
So, I have this problem, I would like to find the average of a column by using the OR function to check criteria from adjusted columns, I tried putting OR into AverageIf function, fail, also tried the "Average(IF(OR(" again not the correct return. Thought it is a simple thing could be done easily but don't know why it doesn't work. So my table is something like this:
ID: Rate Check 1 Check 2 Check 3
1 5 1 1 1
2 3 1 1
3 2 1
4 4
5 5 1 1
6 3
7 4 1
I would like to find the average of the rate column by checking if there are any value in either Check 1; Check 2 or Check 3 columns, so in the above case i will get the average of all but row with the id 4 and 6. Is this possible without using a helper column?
You can use SUMPRODUCT()
=SUMPRODUCT(((C2:C8<>"")+(D2:D8<>"")+(E2:E8<>"")>0)*(B2:B8<>"")*B2:B8)/SUMPRODUCT(--((C2:C8<>"")+(D2:D8<>"")+(E2:E8<>"")>0)*(B2:B8<>""))
If your first ID starts in A2, use this formula (edited to handle empty values in the "Rate" column):
=AVERAGE(IF(MMULT(LEN(C2:E8)*LEN(B2:B8),ROW(INDIRECT("1:"&COLUMNS($C$1:$E$1)))),B2:B8))
I'm looking for a way to compare multiple rows with data to each other, trying to find the best possible match. Each number in every column must be an approximately match the other numbers in the same column.
Example:
Customer #1: 1 5 10 9 7 7 8 2 3
Customer #2: 10 5 9 3 5 7 4 3 2
Customer #3: 1 4 10 9 8 7 6 2 2
Customer #4: 9 5 6 7 2 1 10 5 6
In this example customer #1 and #3 is quite similar, and I need to find a way to highlight or sort the rows so I can easily find the best match.
I've tried using conditional formatting to highlight the numbers that are the similar, but that is quite confusing, because the amount of data is quite big.
Any ideas of how I could solve this?
Thanks!
The following formula entered in (say) L1 and pulled down gives the best match with the current row based on the sum of the absolute differences between corresponding cells:-
=MIN(IF(ROW($C$1:$K$4)<>ROW(),(MMULT(ABS($C1:$K1-$C$1:$K$4),TRANSPOSE(COLUMN($C$1:$K$4))^0))))
It is an array formula and must be entered with CtrlShiftEnter.
You can then sort on column L to bring the customers with lowest similarity scores to the top or use conditional formatting to highlight rows with a certain similarity value.
EDIT
If you wanted to penalise large differences in individual columns more heavily than small differences to try and avoid pairs of customers which are fairly similar except for having some columns very different, you could try something like the square of the differences:-
=MIN(IF(ROW($C$1:$K$4)<>ROW(),(MMULT(($C1:$K1-$C$1:$K$4)^2,TRANSPOSE(COLUMN($C$1:$K$4))^0))))
then the scores for your test data would come out as 7,127,7,127.
I'm assuming you want to compare customers 2-4 with customer 1 and that you are comparing only within each column. In this case, you could implement a 'scoring system' using multiple IFs. For example,:
A B C D E
1 Customer 1 1 1 2
2 Customer 2 1 2 2
3 Customer 3 0 1 0
you could use in E2
=if(B2=$B$1,1,0)+if(C2=$C$1,1,0)+if(D2=$D$1,1,0)
This will return a 'score' of 1 when you have a match and a 'score' of 0 when you don't. It then adds up the scores and your highest value will be your best match. Copying down would then give
A B C D E
1 Customer 1 1 1 2
2 Customer 2 1 2 2 2
3 Customer 3 0 1 0 1
so customer 2 is the best match.
With the following data:
A B
1 CUMULATIVE PERCENTAGE OF ITEMS PRODUCED PER MONTH ("COMPLETION_TABLE")
2 Type Month 1 Month 2
3 KITTENS 0 10
4 FISH 0 20
5 BANANAS 2 5
6 APPLES 0 0
7 PEARS 0 5
8 KITTENS 0 5
9
10
11 PRICES TABLE ("PRICES_TABLE")
12 Type Value
13 APPLES 1000
14 BANANAS 5000
15 PEARS 3000
16 FISH 4000
17 KITTENS 2000
I'm attempting to use the SUMPRODUCT function to calculate the percentage change in each month and use that value as a multiple of the prices table to provide a total price per month across all types that have been produced.
I can calculate the movement as:
=SUMPRODUCT((COMPLETION_TABLE[Month 2]-COMPLETION_TABLE[Month 1]))
... but I then need to calculate the portion of the individual movement values against the price for that type and sum the resulting products together. I have been using various INDEX / MATCH combinations without much luck.
As an example: BANANAS which should =(5-2)*5000.
Written as expanded arrays I would like to do
({10;20;5;0;5;5}-{0;0;2;0;0;0})*{2000;4000;5000;1000;3000;2000}.
Use of SUMPRODUCT implies you want a single figure result. You can use SUMIF as a "pseudo lookup" within SUMPRODUCT to get the prices, e.g.
=SUMPRODUCT(C3:C8-B3:B8,SUMIF(A13:A17,A3:A8,B13:B17))
That would get you a result of 140,000 for your example
From your question I understand the result you want is an array. This is what you get with this formula:
=INDEX($B$13:$B$17,MATCH($A3:$A8,$A$13:$A$17,0))*($C3:$C8-$B3:$B8)
entered as an array formula using Ctrl Shift Enter.
I am sure there is something simpler. I am assuming that the Type in the Price Table are unique:
{=(SUM((A13=$A$3:$A$8)*$C$3:$C$8)-SUM((A13=$A$3:$A$8)*$B$3:$B$8))*SUM((A13=$A$13:$A$17)*$B$13:$B$17)
I'm not sure how to ask this question without illustrating it, so here goes:
I have results from a test which has tested peoples attitudes (scores 1-5) to different voices on a 16 different scales. The data set looks like this (where P1,P2,P3 are participants, A, B, C are voices)
Aformal Apleasant Acool Bformal etc
P1 2 3 1 4
P2 5 4 2 4
P3 1 2 4 3
However, I want to rearrange my data to look like this:
formal pleasant cool
P1A 3 3 5
P1B 2 1 6
P1C etc
P1D
This would mean a lot more rows (multiple rows per participant), and a lot fewer columns. Is it doable without having to manually reenter all the scores in a new excel file?
Sure, no problem. I just hacked this solution:
L M N O P Q
person# voice# formal pleasant cool
1 1 P1A 2 3 1
1 2 P1B 4 5 2
1 3 P1C 9 9 9
2 1 P2A 5 4 2
2 2 P2B 4 4 1
2 3 P2C 9 9 9
3 1 P3A 1 2 4
3 2 P3B 3 3 2
3 3 P3C 9 9 9
Basically, in columns L and M, I made two columns with index numbers. Voice numbers go from 1 to 3 and repeat every 3 rows because there are nv=3 voices (increase this if you have voices F, G, H...). Person numbers are also repeated for 3 rows each, because there are nv=3 voices.
To make the row headers (P1A, etc.), I used this formula: ="P" & L2 & CHAR(64+M2) at P1A and copied down.
To make the new table of values, I used this formula: =OFFSET(B$2,$L2-1,($M2-1)*3) at P1A-formal, and copied down and across. Note that B$2 corresponds to the cell address for P1-Aformal in the original table of values (your example).
I've used this indexing trick I don't know how many times to quickly rearrange tables of data inherited from other people.
EDIT: Note that the index columns are also made (semi)automatically using a formula. The first nv=3 rows are made manually, and then subsequent rows refer to them. For example, the formula in L5 is =L2+1 and the formula in M5 is =M2. Both are copied down to the end of the table.
