Generating Semi-random Numbers?

Jul 26, 2013

How 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.

Generating Random Numbers Based On Probability

Mar 8, 2007

1. I need to randomly generate either a 1, 6 or 12 every time I hit calculate (i.e. F9).

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.

Generating Sets Of Correlated Random Uniform Numbers 0-1?

Jun 25, 2012

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.

VBA - Generating Random Characters In Cell With Format Of Yymmdd / Randcharacters / Numbers

Mar 29, 2014

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.

Generating Random Number List

Oct 20, 2009

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).

Generating Random Outcomes Based On Probability

Feb 10, 2009

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.

Generating Multiple Random Number Sets With Even Distribution?

Oct 14, 2011

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.

Generating Random Number String Based On Alphanumeric String?

Aug 14, 2014

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

Generate Random Numbers In Random Cells

Sep 18, 2009

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.

Generating Average From Group Of Numbers In List That Match Two Criteria?

Jan 29, 2013

So 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.

I am looking for a way to create a random order of numbers in a given range. For example, A1:a100 to be populated with a random number between 1 and 100, but not to duplicate, using every possible number within that range. I use the RANDBETWEEN function to generate the numbers, but I cannot prvent them from duplicating.

How can I use a macro on a button in SHEET 1 to generate random numbers on SHEET 2 as follows?

Cell A1: (1-10)
Cell A2: (1-6)
Cell A3: (1-100)

I've got it working with formulas, but every time I press "DELETE" the random numbers jump to new values.

Random Number Between Two Numbers VBA

Jan 3, 2014

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.

Summing Random Numbers?

Feb 23, 2014

I have a process that generates the value X in cell A1 randomly. So I can change the value of X in A1 by clicking on F9. I want to sum a sequence of X values. I can do this by manually copying each X to a row of cells and then summing the row values. But that is tedious. Can the summation be done automatically without being regarded as being circuler?

Random Numbers With No Duplicates

Jan 30, 2010

I want to set up a column of numbers that will be random without any repeating numbers.

Example: If I set up for 1,000 rows, I would like the random numbers to be 1 to 1,000, but the catch would be to have no duplicates in the column.

It has been several years since I worked with Excel and I am sure this can be done with a macro, but I am not sure how to go about it right now.
