Can Select Array For Correlation Based On Value In A Column?
Apr 23, 2014
I am calculating multiple Correlations for long lists of data. I want the correlation based on the value in a given column. In the below example I would like a different correlation for each value in colA and the correlation will be between colC and colD. ColB lists the different people whose data are used for the correlations. In actuality there are 30 or more people for each test. In every case ColC is the same for a given value of ColB (although I doubt that matters). The number of people taking each test varies. I would like a correlation of ColC an ColD for each value of ColA.
Simplified version of my data
ColA ColB ColC ColD
Test1 Fred .75 1
Test1 Max .80 0
Test1 Sara .90 1
Test2 Fred .75 1
Test2 Max .80 1
Test2 Sara .90 0
....
Test100 Fred .75 1
Test100 Max .80 1
Test100 Sara .90 1

I have defined my last row and column by using:
lr = Sheets("week1").Cells(Rows.Count, "A").End(xlUp).Row
LC = Sheets("week1").Cells(1, Columns.Count).End(xlToLeft).Column
Now how do I select the range starting at A2 through the last used column ( LC ) through the last row ( LR )?

Data example:
AB1AREANumber2SW103SW114SE125NE136SW147SW158SW169NW17
I need a code in VBA that can find the 1st cell in col A that contains "SW" and store the number in col B as V1= # then find the 4th cell in col A that contains "SW" and store the number in col B as V2= #.
so that i can do some math with the numbers. The code should result in 10-15

How do I select a cell based on its row & column count?
For example, Range("D8").Select
Instead of using ("D8") ,I need to select the cell based on its row & column count, i.e. (4,8)

How would you select cell values from differing rows based on the name in an adjacent column. ie, if it says John, add that data to the source data, if not move on.

I have data as follows.
In the first column name of the month is specified.And in the third column of the same row day is specified.And followed by some data in rest of the columns and rows.
I need to copy the data from the presant sheet to a new sheet based on some conditions.
first need to search for the row where the word "MONTH" is there.if it is found then in the same row third column need to be checked for the day like "MONDAY" or "TUESDAY".If it is monday then need to copy 6*8 array of data i.e. (6 rows and 8 columns) into a sheet "MONDAY".if it is TUESDAY then 5*8 array data into a new sheet TUESDAY.And the search should be continued till the end of sheet.

setup:
Columns: c)6:00 AM, d)6:15 AM, e)6:30 AM
Rows: 4)tech1 Phone, 5)Tech2 Phone, 6)Tech3 Phone
What I am tying to do is to select the column that matches the time, for instance anything before 6 AM would select Column C, betweeb 6 and 6:14 still selects column C, 6:15 to 6:29 selects column D, Etc

I'm using excel 2003. I would like to select and copy rows of data within a worksheet of a workbook and then paste those rows into a newly created excel workbook. That is the easy part. The complication is that I would like the macro to select the rows based on a particular string value that will be impossible to specify in a fixed way (i.e., it will change from project to project). Let's say the variable that distinguishes the rows is location, so some are from Tokyo, some New York, and some from Paris. Using vba, how can one 'splice' the data into (in this case, three) seperate workbooks based on the string/values of another variable?
I am familiar with auto-filter, but in this case, I really do need to create seperate workbooks, rather than apply calculations to a selection of the data.

I have a macro that copies three sections of data from a word document and pastes it within the Excel worksheet. The column of data is pasted in a single column (data to be space-delimited and evaluated later), and what I would like the MACRO to do is separate the three sections of data based on the starting and ending values of the section and place them in different columns.
Section 1 : starts with the word "Team"
Section 1 : ends with the word "City"
Section 2 : starts with the word "Location"
Section 2 : ends with the word " Date"
Section 3 : starts with the word "Member"
Section 3: ends with the word "Age"
So section 1 would be pasted into cell C1, section 2 pasted into G1 and section 3 pasted into J1.
Each section will have vary in number of rows between the starting/ending values, so to cut and paste the section based on the starting and ending value is vital.

I have a user form that has one combo box on it that right now references one column of data.
Now I am being asked to have three columns of data and the combo box to show one of the three when a certain criteria is met.
I believe it would be easiest to have an additional combox with a change event when the box is populated with "whatever" in the field
So S:3 to S:5 have A, B, C
And EC:1-EC:59, ED:1-ED:59, EE:1-EE:59 contain the data that should show when S:3, S:4, or S:5 is selected.
If S:3 is selected then the list in EC:1 - EC59 would show and so on.

I'm only starting to get to grips with arrays. I have what I consider to be a lot of data that I need to 'cut' into separate workbooks. I have written some code that does this by simply looping through each line, 250k+, checking against a variable and copying the row into a separate sheet. This took longer than it would have doing it manually. It was suggested to me that I use arrays to speed up the process. I have managed to store the test data into an array but am struggling to find a way to loop through and pull out an entire 'row' from the array based on a variable. I have looked for 2 days in various places to find some way to loop through the data held in the array, but to no avail.
That code will appear here from about 8am GMT tomorrow. I know that once I've cracked this I'm on the road to some very significant time saving and comprehensive report writing.

I am trying to select specific values within an array.I have two tables, weight table and a factor table. These tables are a lot bigger than the example. I am trying to multiple the weights times the corresponding factors and then sum the result in one cell using arrays.
The third table is the result I am looking for. However, I would like to use some type of index/match or choose to get the result but cannot figure out how to do it. A couple of functions that I tried that did not work are next to it.
The index fails because the index function does not output an array (The result of the index function is just 4% instead of {4%,3%,4%}). The choose fails because the choose function does not select values within an array (ie I would have to put each factor as a separate value (F4,G4,H4) rather than the entire array (F4:H4). There are so many factors that I would like to avoid that.)

I have a problem with a listbox on a userform. I have an array that is stored in a name. The array has 2 columns and + 1000 rows. It looks like this:
100 Name1
110 Name2
120 Name3
Etc.
The listbox is filled from the array:
Private Sub UserForm_Initialize()
frmZoeken.lstbx_Gbr.Clear
frmZoeken.lstbx_Gbr.ColumnHeads = False
Dim myArr()
myArr = Evaluate("varRekSchema")
frmZoeken.lstbx_Gbr.List = myArr
End Sub
When the form with the listbox opens, it has to select by default the value in the listbox that corresponds with a value in a cell in the workbook:
Private Sub UserForm_Activate()
'On error resume next
frmZoeken.lstbx_Gbr.Value = Cells(ActiveCell.Row, 3).Value
frmZoeken.txt_Zoekterm.SetFocus
End Sub
When opening the userform the following error message appears: Could not set the Value property. Invalid property value.
When I activate the row "On error resume next" the listbox is correctly filled. The error occurs with selecting the default value.

I need to query table contents where some general items are met, and item id's are not contained in an array.
Example:
Code:
SELECT LOOKUP.*, LOOKUP.Var FROM LOOKUP WHERE ((LOOKUP.Name)="test" Or (LOOKUP.Name)="test2" AND ((LOOKUP.Type)=3) AND ((LOOKUP.Var) ("array", "of", "items")))
I need to know how to add an array to a query since I can't hard-code the list each time, and the array can be a different size each time, so using array variables doesn't make sense here.

I am trying to do something that sounds fairly straightforward but have not been able to achieve the final result.
I have a sheet which has multiple range addresses stored in different cells and so far I have been able to pass the Range address to Range variables by looping through a range array. Now I would like to select these multiple ranges. My code looks as below;
VB:
Dim Cnt As Integer
Cnt = Sheets("Sheet1").(Range("1040").Value ' Cnt holds the the total number of ranges to be specified in Sheet1
Dim RStr(1 To 80) As String ' This will hold the range addresses specified in Sheet1 in cells C1041 to C1120. Upto 80 range addresses could be specified.
[SIZE=2] Dim Rng(1 To 80) As Range ' This will store the ranges based on the range addresses stored in RStr()
Dim i, j As Integer,
[Code]...
I am not sure on how to select multiple ranges using range array hence tried Union() however it is obviously not correct and throws an error.

concerning the use of correlation in vba. What are my options when i want to calculate a correlation within vba. The variables are all still within vba.
Who knows what formula's i could use to keep everything within vba.
If you don't understand my question please ask so i can try to make it more clear.

I have code to create a correlation matrix (NxN, where N is the number of columns). This is done by selecting an area that is NxN, entering the function and range, then hitting ctrl +shift + enter (array formula).
However, I want to convert this to accept VBA arrays, rather than a data range, and give the output in form of an array as well.
VB:
Function CorrmatK(dataRange As Object) As Variant
On Error Goto 20
Dim r As Integer, n As Integer, rr As Integer, i As Integer, j As Integer, k As Integer, doit As Integer
Dim x() As Variant, mc() As Double, ss() As Double, m() As Double, ob As Object
r = dataRange.Rows.Count
n = dataRange.Columns.Count

I am in the unfortunate position of having to run about 900 correlations with Excel as my only option. Normally this would be fine, but in this case, I need the Pearson's test of significance. The only way I know how to obtain this in Excel is through using a regression, which is incredibly time-consuming. Does anyone have a suggestion how to make the best use of time?

I am using excel to do a monte carlo analysis of a process. Until now, all my distributions have been uncorrelated, but from now I would like to produce distributions with a given correlation. This is a fairly easy process for normal distribution, but in this case one of the distributions is Weibull and the other lognormal. I don't have a stats background, so how to implement this. Producing the two distributions is no problem, but I would now like to be able to alter them or the original formulae so they are correlated properly. If it would greatly simplify the process, the lognormal distribution could be replaced by a normal, but not the weibull.
The formulae I'm using for each is:

I wasn't able to attach the file because it was too big, but you can download it from here www.easygcc.com/correl.rar. On the sheet called " Correlation" there is matrix, I am baiscally trying to fill in the correlation formula into every cell so the matrix is filled out. The data for the correlation calculation comes from the sheet called "Tech Data". I have filled in the correlation formula into a few of the cells as an example, but I don't want to continue doing this manually but rather have a macro do it for me. Otherwise this will take for ever. My macro is also a part of the file, if you would liek to look at it and maybe fix what I already have.

On one sheet (KPI) I have either the values "x" or "" in the range A84:A89 to mark wheter to use the corresponding project in the range B84:B89. On the sheet X-ref I have the same project names in range T4:Y4 and a corresponding target value in T8:Y8
What I want is the sum (or average) of the marked-projects target-values. The result should end up in KPI!G31.
In other words I want
=sumif(A84:A89;"x";'X-ref'!T4:Y4)
but it doesn't work since the first range is an column-array and the second range is an row-array.

I have a table that I add rows to via a macro. I am trying to add correlation matrices that find the last row of the table, and include a certain number of rows above that to create a rolling correlation. For example, if I want the 2 week correlation, I would like the last 10 rows of data, but if I add another row, this formula should move down to incorporate the new row and deselect the now 11th day preceding. I do this manually but it is very time consuming.

I am now analysing the ordered correlations of products in a warehouse.For example, I have 16 products (product 1 to product 16) in my warehouse. During last month, there were totally 391 orders (order 1 to order 391). If a product is requested in a ordered, an "X" will be marked as per attached sheet.
Now my goal is to figure out which pair (or even triple) of products are ordered/requested at the same time (or in the same order) for the last month. I intend to use the analasys result to move the more ordered pair/triple products to stay near to each other at the warehouse so it will save the time for picking.
How to do that analysis?

I have a particular issue - i am trying to create a rolling correlation.
lets say you have two variables for 3 different months:
Month1 a x
Month2 b y
Month3 c z
correlation will correlate a-c with t-v
however, come next month - i have to manually drag the ranges for a rolling three month correlation:
Month1 a t
Month2 b u
Month3 c v
Month4 d w
correlation will now correlate b-d with u-w for a the last three months.
I want to automate this as I know what the month is, I can't seem to return the last three months and correlate the data.
I have tried to do this with the database functions, but I think that they break the array relationship of b-d and u-w in the correlation function.

I'm trying to Pearson Ranks correlation table. This is the formula I'm
using:
=PEARSON(Ranks!$B$3:$B$230,Ranks!B$3:B$230)
This is placed in cell B3. When I copy the formula over to DT3 the formula
correctly adjusts the B in the second part of the formula all the way to DT
and still references the values in the B column.
But I want to now copy this down to C4, D5, E6 and then over to DT for each
so that it correctly makes the correlation table.
