View 2 Replies View RelatedHow to generate semi-random numbers? I have a small sample (26 points) that I would like to extrapolate out and plot on a skewed bell curve. The numbers represent a ratio which can never be less than one. The average of my sample is 1.0149 and the standard deviation is 0.01234. When I use the random number generator tool in the data analysis pack, it generates mostly good numbers, but it also produces numbers like 0.98 and such that are never possible in my data. I've made a plot with the random numbers, including the sub-one ones, and then just adjusted the x-axis so that they wouldn't show on the graph, but I know that that's not the correct way to do it. My graph isn't skewed as much as it should be.

2. I want to specify the probablility of each result. For example, I want 12 to be the result 80% of the time, and 6 and 1 to be the result 10% of the time.
I need generating 40 rows (Columns of 17 (Columns A - Q) Random numbers (1 to 5) that will sum to specific values (60, 55..) in R Column, and to regenerate it on pressing any key.
The same has been done for one value in [URL] ..... but I need it for a set.
I'm looking to generate correlated random unifrom numbers between 0 and 1 using the excel random number generator, rand(), and a user defined correlation matrix - without the use of a plugin. I realise there are plenty of risk plugins I could use, but was looking for something excel/vba reliant so I could distribute it without the user having to install anything.
I've tried using a cholesky matrix, but most of time it resulted in one of the numbers being 1, and higher that all the others.
I have a spreadsheet of 1000+ companies and I want to take a random sampling of 100 of them. I would assume this could be accomplished by auto-filling a numerical value to each line of data (which I did), then scrambling only the column with the numbers (which I can't figure out), and then selecting the entire text and resorting it to put the numbers back in order and then just work with the first 100 rows (which I can do, if I knew how to make the numbers random).
I would like to ask if there's a way to generate a random 4 characters in one cell and the specific random 4 characters that has been generated will be copied until the last cell of my preferred choice?
The format that I want is that:
yymmdd / random 4 characters that has been generated / 4 numbers that will increment sequentially
For example:
in A1: 140330QWER0001
in A2: 140330QWER0002
in A3: 140330QWER0003
.
.
.
.
.
But here's the catch, the file that I am using when closed then opened again will generate another random 4 characters with the same format. If i opened this file tomorrow:
for example the date for tomorrow is March 31, 2014, the file will do:
in A1: 140331TYUI0001
in A2: 140331TYUI0002
in A3: 140331TYUI0003
.
.
.

I tried to record it, the Rand() function when copied will generate another 4 characters.
I've managed to write a random number generator that produces multiple sets with no repeating numbers per a set.
Now, to step it up a notch, I'm trying to create an even distribution of the numbers generated which is where I could use a hand. Here's my current code:
Code:
Option Base 1
Sub RandomNumberStrings()
Dim rndno As String, strg As String, msg1 As String
Dim r1() As String, r2() As String
[Code]....
Equaling 500 numbers generated as intended, but my target is to get every number with an equal frequency.
Wondering if it is possible to generate a random 4 digit number based off an alphanumeric string?
Example;
Cell A1 has 123XVF1234
Cell A2 has 321AFW4321
In B1 I would like to have a 4-6 digit number that is generated based on the alphanumeric data in Cell A1 (and so on down the list). If that is possible, I would also need to be able to convert back the 4-6 digit number back to its original alphanumeric value
Example;
If B1 returns 643562 it would need to be able to be converted back to 123XVF1234
Can anyone help, I'm trying to create some test data, eg 1000 rows in excel. In each cell a formula (?) returns some text such as Dog, Cat or Rabbit based on the probability Dog=0.5, Cat=0.3, Rabbit=0.2
I've come up with a messy solution of generating a random number between 1-100 and then using a lookup table where 1-50 = dog etc... it works but is long winded and difficult for other people to follow.
I have build a system that needs a lot of random numbers generated to work.
I have used what I thought would work to generate me these numbers like this example:
VB:
Lastrow = ThisWorkbook.Sheets("RPlay").Range("A" & Rows.Count).End(xlUp).Row
RPlayerNum = Int((Lastrow - 2 + 1) * Rnd + 2)
This would generate a random number into RPlayerNum variable, based on the list in sheet RPlay, missing off row 1 as the header.
However we have noticed a massive flaw in this code.... It works as long as the excel file is open, each time run it gives a different random number. However if you close the excel file and open it, then run it, it ALWAYS gives the same number first run, every time.
I need excluding text from a cell and come out with a random number up to 3 numbers. Please see the attached image;
If you notice in column D there is text and a number that starts with a decimal, for example on the first row is .437 the next row is .215 next row is .63 etc... Is there a way to come out with a random number mixing it up to 3 digits and output those number on column "E"? Im only interested in filtering and coming out with the random number i mentioned .437 .215 .63 etc... not the +/-.010in.
There is no right or wrong number, i just need to come out with random number using up to 3 numbers up.
Maybe for .437 three numbers up could be .440 for the next row .215 maybe a number up .216..etc..
Hope there is a way to do this, my excel file is too long to type a number manually.
I vant to get a random number i a cell whenever my file is opened, but the random function is not working well for me as I always get the same number.
Sub Auto_Open()
MyValue = Int((99 - 1 + 1) * Rnd + 1) ' Generate random value between 1 and 99.
Range("A1").Select
Selection.Value = MyValue
End Sub
I'm using the prob() function, and it works for no more than 61 random numbers. Does anyone know of a limit on the number of random numbers used in the function, and whether it's possible to use more numbers in the function? My formula is:
=PROB($C$11:$C$71,$L$11:$L$71,G11,H11)
I want to create a long list of 10,000 random numbers between -100 and +150, but do it so that the average of all the random numbers equals 20.

I am working on a Random Cycle Count Generator that provides random SKU#s based on 3 separate columns of SKU listings. The user clicks a button to generate the SKU#s to cycle count for that day. What I would like to see is a date stamp in the columns next(B,D,F) to the referenced SKU listing(A,C,E) based on which SKU#s are generated. This will let me see the last date that the SKU was generated. I would also like it to automatically save after generating.

View 9 Replies View RelatedSo we had a month long, company paid (woohoo!) "weight watchers" challenge. On 1 worksheet ("Stats"), I have the Name of every Employee (A Column), then their Start Weight (B Column), End Weight (C Column), Department (D Column) and finally Location (E Column).
I know how sensative some people can be about their weight, so I locked the page and created another worksheet named "UI", which will display the "Average End Weight" for each department. So Human Resources would be the department in cell A2 on the UI sheet, with City 1 being the Column Header in cell B1. There are 8 cities (offices) and 23 departments.
So, for cell B2, I want to scan through the "Stats" worksheet and locate all of the cells in the department and location columns that read "Human Resources" and "City 1" respectively. Then grab the "End Weight" for every row that meets these 2 criteria, add them up, and divide by the number of "End Weights" that were grabbed.
My solution would be to make a separate column for each department (and then each city, so essentially 8 columns to represent all the cities for each department), use a nested (maybe 4) IF statements to then list only the end weight if that particular row meets the criteria, then at the bottom of each separate column, add all the shown numbers up and divide, then draw the information from THAT number into the "Average" cell on the UI worksheet. But it isn't very dynamic and if i want to use this sheet next year, there will be more employee info to be added and it would be a mess..further more, it would be...what...23 Departments x 8 Cities x 155 employees = ~28,500 added cells.
with a code to generate new sheet name and running number.
For example the name can be INF001 then follow by INF002, INF003 .... each time I run the code.
I am using Excel to produce work orders and I need each one to have its own unique number. Much like an invoice or contract number, each time I open the file I would like Excel to generate a new number for that spreadsheet with a value of 1 more than the previous spreadsheet.
