I am experimenting with solver and have attached an example of my problem.
A3:A12 contains a list of numbers from 1 to 10. B3:B12 are my cells I wish to change to be either 1 or 0. If a cell in column B equals 1 then it multiplies the corresponding number in column A by 1 and puts the result in column C. Column C is summed up in cell C14.
My solver settings are below: ...
I have the following dataset and was wondering how I can run a constrained regression in Excel with the constraint being that the total allocation of assets is 100%:
Total return (y): 12 data points
Asset 1 (x1): 12 data points
Asset 2 (x2): 12 data points
Asset 3 (x3): 12 data points
Asset 4 (x4): 12 data points
Asset 5 (x5): 12 data points
Asset 6 (x6): 12 data points
[Attached is a spreadsheet with the actual dataset]
I know the regression equation I need is R = b1X1 + b2X2 + ….+ (1 - b1 - b2 -….- b5 )X6 + e
I have a cell, D5, which is the sum of three other cells, A5 B5 and C5. (all currently empty). Cells A1 through C4 are filled with various numbers.
What I've been trying to do is use solver to say: Make D5 equal 200, do it by manipulating only A5 B5 and C5, and make it subject to the constraint that A5 must equal a value selected from A1:A4, and B5 must equal a value from B1:B4, and C5 ...etc. I have deliberately set it up so that there is only one solution.
I was doing fine until trying to create the constraints. How can I make a constraint that says "this cell" must equal "one of the following cells"? And if I can't do that, is there an alternate method of achieving the same result?
I am trying to convert Degrees Minutes & Decimals of a minute (12° 34.567') to Degrees and decimals of a degree (12.57611°). I have the formula to convert latitude, that is two digits, but it doesn't want to work with longitudes, three digits. (see attachment). This is the formula that I am using:
=IF(A2="","",(INT((LEFT(A2,3)+MID(A2,4,6)/60)*100000)/100000)&"d")
I have to use use the solver to calculate something (a mean-variance framework).
I am using the solver to minimize a cartain cell (variance) by making two cells equal through (expected return) by varying 10 cells( weights of assets), but I have to repeat this for 500+ times (for different expected returns).
Someone told me that I could best use some sort of loop through VBA. But I don't have a clue how that works.
I have a userform where I have 2 comboboxes. The first combobox shows the the first column (only 1 of each) and the second comboBox shows me the secondary list that correlates to the valuse in the first from column B. Now I have a text box that I am trying to get the value from column C depending on what I have in the first 2 comboboxes. What is the easiest way to do it? This is all in VB since it is a UserForm, and using Vlookup seems to be too many lines if I go that route. Is there a way to use Index and Match in VB where it would be more efficient? I attached just a sample of how the data would be layed out in the Excel sheet.
View 4 Replies View RelatedI have a variable called "MinVal" which is an integer. Does anyone know the correct code for rounding this integer to the nearest multiple of 5 (or 10)? I need to do this in VBA, not on the Excel worksheet.
View 4 Replies View RelatedI want to use solver program. But when solver "changes cells" i want it to trigger my pivot tables in the workbook. So i added the code to my worksheet:
Private Sub Worksheet_Change(ByVal Target As Range)
ThisWorkbook.RefreshAll
End Sub
So when a change occurs, all my pivot tables will get refreshed and my data will change. Is solver able to trigger this event while solving an optimization problem?
I am trying to add some numbers only if they are integers/numbers. My condition goes like this:
IF((rangeA)=Numbers,SUM(rangeA),"One or more values not available")
I came up with this formula, but it gives me an error.
=IF(ISNUMBER(P5;Z5;BL5;BN5;BP5;AS5;AV5;EU5;FI5;GH5;GK5;GN5;GX5;HE5;HR5);SUM(P5;Z5;BL5;BN5;BP5;AS5;AV5;EU5;FI5;GH5;GK5;GN5;GX5;HE5;HR5);"One ore more values not available")
It says I have given many arguments for ISNUMBER function.
The only way I can find under "Conditional Formatting" to highlight round numbers is to set a formula.

How can I generate a list of all possible combinations of the integers?
I am using to rotate through different values of 2 variables. The macro was created by a friend of mine 2 years ago so I need to modify it. The macro is quite usable so I hope someone will benefit from it. The problem with it is doesn’t rotate through a range of integers but only from zero to some number. In other words it allows to specify only the right hand of the range through which it will rotate (for example, from 0 to 100 or from 0 to 20 for A). The second issue with it is that it adds a difference number (“dif”, e.g. 3) to the start of the second variable’s range and starts only from there (from 3 to 100 for B). The third issue is that it doesn’t allow to rotate through a third variable (“C”) as you will see in my example. I am working on a task which requires precise definition of the ranges through which the macro will rotate and also the ability to rotate through a third variable. Need to modify it so that all the three imperfections are removed from it? Or maybe there are ready made macros freely available which allow to do just that?

View 3 Replies View RelatedI recently had a major system crash. Took me a couple of hot stops and starts to get my XP professional to behave. It seemed to sort itself out and all is now working fine except that is for excel 2010 part of office 2010 personal and business. I first installed Office 2010 in January this year and it has all worked fine. Now Excel spread sheets behave as follows - even those that were created before the system crashes mentioned above. If I enter integer 1 in any cell and press accept the entry becomes '0.01'. If I enter 1.0 the entry becomes 1 when accept pressed. I have repaired the Office suite. I have removed and reload the Office suite. I have tested numbers in Word and on the calculator and both work correctly - so my question is simple - How do I make Excel once again accept that a single digit should be taken at value and not convert it to tenths?

Suppose you have 3 variant Arrays, named sArrPos1, sArrPos2, and sArrPos3.
What is the syntax for using an integer variable to specify which of the three to work with?
E.g.

I want to work with sArrPos1 first, then sArrPos2, then sArrPos3, but can't hard type them.
I needed to convert PartNumber to a string using Cstr(PartNumber).
The following VB code searches an Excel spreadsheet for a Production Order and then looks for a Part Number in the corresponding row. The Production Order can be listed multiple times, but there is only 1 Production Order/Part Number combo. When searching for the Part Number, it will find letters, numbers with a dash and letter/number combos, but won't find integers.
For example, it will find ABC, 3500-01 and T1000, but not 200.
is it possilble to extract integers from a text string within a cell?
Eg.
Cell A1 - "ABC 123"
I want to extract the "123" from cell A1.
I have many text strings from which I need to extract the integers from.
The trouble is that each text string does not follow a consistent order, so I
cannot use text functions such as LEFT, MID or RIGHT to extract what i need.

I'm trying to round off my numbers to specific integers. Sorta like a step function (in algebraic terms).
For example, my first few integers are 0-8-13. I want: 0<=X<8, 8<=X<13, etc.
So far, this is what I have: ...
I have a lot of lists of integers and I want to sum their Xth power automatically, for X = -3, -2, -1, -1/2, 0, 1/2, 1, 2, 3, 4, 5, 6.
For example, take this short list of integers: 1 2 3 4 6 12
The sum of their Xth power must be: 1^X + 2^X + 3^X + 4^X + 6^X + 12^X
How can I do that?
I need to declare a two dimensional array that will return the Row and the cell's string value. My only solution is to return the row as a string like this.
Public GlobalArray(2, 100) As String
How to get more control than this? Maybe I should just declare it as a variant but this might open it up for problems later.
I have a comma delimited CSV file that holds about 2 millions rows of data (a lot I know but it's the only format I can work with unfortunately). One of the rows has some numbers in it that have lots of decimal places (like 3.908651901). I need to round that entire column - all 2 million rows - to whole integers.
The problem is that when I open it in excel it says something like "only 1 million rows shown". After more investigation I have found out that excel cannot handle more than 1 millions rows at a time.
My question is this: If I select the whole column and round the numbers to integers will that apply to the entire 2 millions rows? Or only the 1 million showing in excel?
Are there any other programs available that can handle 2-2.5 million rows and change the column to whole integers?
I have a linked text box and spin button on a userform so the user can enter text or use the buttons and I'm having trouble barring non-integer inputs! Here's what I have so far:

View 6 Replies View RelatedI have tracked down an overflow Error 6 to the following line:
dMax = Int(s * DPoints / SPoints)
Where all variables are defined as Integers. The error goes away when I define s as Long, but I don't understand why this should be required since none of the individual variables ever exceed the scope of an Integer (-32768 to 32767).
Strangely, I get the same overflow problem when I type either of the following calculations in the immediate window:
? Int(328 * 100 / 1000)
? 328 * 100 / 1000
? 328 * 100
Note that no variables are defined, so why the overflow problem? Surely Excel/VBA should be able to work with this very basic calculation without any problem, by assigning the appropriate dimension, no?
Is this a known problem with Excel/VBA?
I am using Windows 7, with Excel 2010 (updated from 2009).
I am trying to drive Solver in Excel 2000 with a Visual Basic (version given as 9969) macro. SolverReset is observed, and SolverAdd puts the constraints in. But the SolverOK statement does nothing, so the SetCell and the ByChange windows stay empty.
SolverSolve is trying to do something, because the spreadsheet cell that should receive the return code from Solver gets an error value #VALUE! (The macro then stops, unable to process this entry.)
Solver is checked off ok in the References list in V.Basic.
The same macro, same spreadsheet, in the same Excel file, works fine on the other computer in my office with what I am told is a more recent version of Excel; i.e. this doesn't look like a coding error.
