VBA To Perform Weighted Ranking From Array Of Data

Oct 12, 2011

I'm trying to achieve a table of weighted ranking based on correlations, a table I already have like the one given below

John / Products Owned 1 2 3 4
Shoes Socks Polish Brush Lace
Trousers Shoes Socks Belt Polish
Wallet Belt Trousers Shoes Socks

What I'm trying to achieve is this:

for all the top 4 correlations given for each product owned, i need to consider the ones not owned by John and recommend overall rank of the following nature:

For instance, the rank of socks here will be (1+2+4)/3 = 2.33, the rank of belt will be (5+3+1)/3 = 3 [ I'm considering the rank of belt as 5 for shoes, since it doesn't occur in the top 4 ]. Shoes, here will not be ranked since it is already owned by John.

I'm struggling to translate the logic into code here. Currently I perform it in a cumbersome manner, copying all columns to one column, then performing a pivot to find repetitions and so on.

Perhaps there's a function that could scan a dynamic sized table here, find the unique items and number of times they're repeated?

Loop Through Array And Perform Formula

May 10, 2006

trying to loop through an array, with each loop calculating a formula (VLOOKUP) for one cell based on the values of a cell in another sheet.

Not sure but I think it has something to do with looking up a text value while the loop returns a value.

Private Sub ExpandFormula()
'calculates Counttarget formula in COUNTTARGETS sheet across required range
Dim CellsDown As Long, CellsAcross As Integer
Dim i As Long, j As Integer

Histogram From Weighted Data

Jan 12, 2010

I'm trying to use the 2007 histogram tool (or frequency) to show me the frequency of data, but my data is in a different form than required for either of these tools. Let me use the following simple case -- to show the frequency of student grades both tools assume I have a list of student's test grades. What if I instead have more than one column, e.g., "grade" and "number students with that grade"??

My application is actually different, but it's still 2 columns, a numeric property and a weighting factor (e.g., fraction of the total).

If Cell Is Blank And Data In H Is A Certain Value Then Perform VLookup

Feb 4, 2014

Possible to have two spreadsheets and then perform the following tasks

1. Check If the cell in column I from cell I4 and the spreadsheet varies in length is blank and if it is - see item 2

2. The data equals certain values i.e. CDE or CDE - QUO or CDE - PRO - see item 3

3. Perfom a VLOOKUP to another spreadsheet

If the routine stops at any of the items then move to the next cell

Data is on spreadsheet - Allocations.xls
Vlookup is performed on this spreadsheet - 001 - Allocations - Blocks

The Vlookup for example is: =VLOOKUP(A5,'[001 - Allocations - Blocks.xls]CurrentDayAll'!$1:$65536.9,FALSE)

Ranking Without Zero And Ranking On Multiple Factors?

Aug 12, 2014

I am facing some problem with ranking formulae. Attached is a file illustrating them.

Problem 1: Ranking without zero I have a set of data for products. They have a number next to it. Some of the products have a ZERO value next to them. I want to rank the data in an ascending order while ignoring the products with ZERO value next to them.

Problem 2: Ranking on multiple factors I have a set of data for 50 products. There are 5 factors based on which I want to pick the best and the worst. Each factor has a value which can be a negative number, zero or positive number.

This is what I am doing presently: Ranking the products on each factor in a separate column. Points are assigned based on the ranking, i.e. if the ranking of "product A" on Factor 1 is 32, then it gets 32 points It is assumed that equal importance [weight] is given to each factor, thus average points is calculated based on ranking of each product on each factor. Average points are again ranked in descending order The top & bottom 10 are picked from this ranking.

Number of products and number of factors can be different for each analysis. Presently I am giving equal importance to the rankings for each of the factors, what if I have to give varied importance [weight] to the factors.

Automatically Sort Data And Ranking Based On Sorted Data?

May 22, 2012

In the attached spreadsheet I track the performance of my team. I enter the AHT for my team in the work sheet named "AHT Summary".I keep updating this data every month. automatically sort the updated data and rank the agents based on their average AHT. The person with the lowest AHT should be ranked 1. Column is highlighed in green for your reference. Based on this ranking the work sheet named "Ranking" should be updated automatically. Since I am taking a weighted average for all agents, the one who gets the lowest AHT should be ranked 1st . In the ranking work sheet the agent with ranking 1 should be given 100, the second highest ranked person should get 98,third 96,fourth 94 etc.

Ranking By Data In Two Columns?

Apr 4, 2014

I am trying to rank via data in two columns to eliminate any tied rankings.

I need to use the data in columns "AW" & "AX" to compile the rankings.

The ranking needs to be calculated by the highest number in column "AW" being ranked #1 and the second highest ranked #2 etc etc......any ties as a result of this ranking need to be broken by the lowest number in column "AX", the lower number being the higher in value and thus being the higher ranked.

For example:


13 89 7
13 63 4
14 89 2
14 81 1
13 90 8
13 66 5
13 58 3
13 87 6

I have attached the spreadsheet that I am using.

Ranking Without Distorting Data Order

Aug 20, 2014

Ranking in excel.

Column A - List of students Names
Column B - Grades of Students
Column C - Rank

The problem is, when I rank the students (order highest to lowest) the data in A and/or in B also moves.

What I want to accomplish is that the data input in columns A and B stay as is and Column C shall indicate what is the ranking of that student according to the number of data entry. i.e. 1st, 2nd, 3rd or 1,2,3 respectively.

Group Data For Ranking & Sorting

Mar 19, 2009

I have a spreadsheet with a list of ID's in column A. In Column B I have a list of ratings. Each ID has more than one rating. For example there may be 8 rows with ID 1, 12 rows with ID 2, 6 rows with ID 3 etc......

I want to rank the ratings in Column B with highest being 1 but only when the ID's are the same. For example there would be 8 ratings ranked for ID 1, 12 for ID 2 etc.....

The problem is I am running a monte carlo simulation on the rating of around 10,000 simulations. Every simulation the rank for each row will of course change because the rating has changed. The spreadsheet has around 70,000 rows and over 3000 ID's.

How can I do this without either the computer becoming a crawl or freezing up and it not taking 30 minutes for each step of the simulation?

Weighted Average

Jul 25, 2007

I have a large dataset that includes information on the investment payout ratios of US companies over the period 2004-2006. I need to calculate the weighted average investment ratio for each company---see sample below

Microsoft Excel - example.xls ....

[HtmlMaker 2.42] To see the formula in the cells just click on the cells hyperlink or click the Name box

The corresponding weight for each year must be as follows: 0.5 for 2006, 0.3 for 2005 and 0.2 for 2004. Then, for company A, the weighted average will be: (0.5*B2)+(0.3*C2)+(0.1*D2) = 7.8 (see cell E2)

The problem is that for some companies there are missing data for some years. For example, for company B, there are no data available for year 2004. In this case , the weights have to change to 0.6 for 2006 and 0.4 for 2005. Then, the weighted average investment for company B will be (0.6*B3)+(0.4*C3) = 16 (see cell E3). Similarly, in cases when there are data for only 1 year , the weight has to change to 1. Then, for company C the weighted average is 35 (see cell E4)

Is there any formula to give me the weighted average as it appears in column E without having to adjust it for each single case?

Weighted Scoring

I have a set of data about a persons monthly spending habits on

Food 300
Entertainment 200
Clothing 100
Transport 260

The pre calculated budget allowance for the month was 500

I would like to write a formula that would do the following; give the person an score out of 1.1-10 based on how well he spent on the above items which are in order of priority (i.e. it is better to spend more on food than on entertainment etc) And then an over all score (1.1-10) that will reflect how well they spent.

Weighted Average In VBA

Nov 10, 2009

I have a spreadsheet which basically looks like this

2, 5, 15, 20
2, 8, 12, 13
2, 7, 19, 46
F, 1, 10, 26
P, 1, 10, 39
P, 6, 22, 89
P, 7, 14, 46
P, 2, 11, 14

Column A is the key. If multiple rows have the same key, they're related.

The last column (DX on my spreadsheet) represents minutes participated, and is the weight variable. The middle columns are data that I'd like a weighted average for.

Here is the output I'm looking for given the above example:

2, 6.66, 16.83, 79
F, 1, 10, 26
P, 4.91, 16.73, 188

Column A remains the same, with one row for each key. The middle columns have their weighted average (where 6.66 = (5*20+8*13+7*46)/(20+13+46)), and the final column (DX) is the sum of minutes for all like keys.

Weighted Average ...

Nov 16, 2009

I have long lists of data which has name of manufacturer, number of items and fault rates of items.


Manufacturer.......Number of Items......Fault Rate

I need to find the weighted average of each manufacturers fault rate for just themselves, and also how the average of all the manufactueres would be if they weren't in it.

So for example for Dell I would need their weighted average of their three data entries and also then the weighted average of Sharp, Microsoft, Panasonic together.

I have been doing this by splitting the data into sections so for the example above I would do:

Manufacturer.......Number of Items......Fault Rate

I would sum the Dell items, then sum the number of items excluding Dell then do two weighted average calculations giving me the ones that include then the ones that exclude Dell.

Then I would do...

Manufacturer.......Number of Items......Fault Rate

And do the same process but with Sharp totals etc then move onto the next one.....

This example is with a very small data set so I'm sure you can see that this process is very time consuming, but I don't know any other way of doing it without splitting out the data first.

For example: If a V is entered in any cell in their attendance worksheet, I would like for a 1 to display under the vacation total column. The next time a V is entered in, I would like it to update the cell containing the vacation days used for the year to 2. If a 1/2 V is entered, a .5 would be added to the total used.
