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.
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.
im given an area and im asked to generate 10000 random numbers. how can i?
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.

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 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.
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
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'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.
I have two data sets one measured and one modelled and I am testing a conceptual model that proposes that only where the tails of the probability distributions of each data set crosses will you experience an event. I'm enclosing an example file which contains both data sets and some descriptive statistics as well as the associated histograms and a diagram of what I'm ultimately trying to achieve. My question is how I go from the data sets I have with such a large discrepancy between them to plotting their probability distributions?

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 2 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.
I am looking for code that can generate the report that a user selects.
For example the user clicks reports on the userform. The report userform opens up. The user checks the monthly report button and enters the last day of the month he wishes the report to be for. i.e 7/31/2010 and then clicks generate report. when executed excel creates a new workbook and creates two sheets. the first looks exactly like the master data sheet from the original worksheet but of course with the specified data. the second sheet will populate a summary of the data. I will address that after i figure out how to get the first sheet compiled.
I am trying to create a spreadsheet for an online gift registry. They require that the spreadsheet have the photo's url's in a column. I already have the spreadsheet filled with my data. In the spreadsheet, Column D is filled with unique numbers, some with parenthesis, (ex. 52011, 52011(2), 34132, etc.)
I also have a folder full of images that are similarly formatted as such
"...imagesrand_name_52011.jpg". (They will be moved eventually to a webserver.) Each number in the column may or may not have a corresponding image. And the images may or may not have a corresponding number in the spreadsheet. Is there a way to generate a url automatically in a column that corresponds to the image with the matching number? And if it doesn't, just leave it blank?
So basically I have a spreadsheet that tracks if a patient has turned in there required paperwork within the last 6 months and then changes the cell to white and lets me know how many days they have left until they are due to turn this paperwork in again. Then if it has expired I have a condition format change the cell to Red but I would like to add in the text EXPIRED to the cell. lastly I have Cells that have no data in them gray and I would like to add in red text saying No Paperwork.
I'm hoping this will be my last build of this spreadsheet so I can go ahead and start applying it to the real workbook [URL]
I am attempting to find a way to search through a database I created based upon every day of the year. My goal is to have a user input a beginning date and end date for a trip, then my functions will return the range specified with each day and it's individual temperature average (in my database).
I also need generating the dates between the start and end dates that are entered by the user. I was considering combining Days360 with an Hlookup that searches through a massive sheet with all the dates for the upcoming year and then going down 1 in the column for the difference in the dates in each column.

I would like to generate a dynamic list of the top five most common text responses in a range. For simplicity sake, let's assume that the range spans cells A1 to A20, and the list is generated in cells B1 to B5. So, essentially, I am seeking five separate formulas. One to calculate the most common text element, one to calculate the second most common text element, one to calculate the third most common text element and so forth.
I am currently working with the two formulas below but finding it incredibly difficult to merge them into a working format.
Formula for finding second most common number:
=MODE(IF(IF(A1:A20"",A1:A20)MODE(IF(A1:A20"",A1:A20)
),IF(A1:A20"",A1:A20),""))
Formula for finding most common text element:
=INDEX(A1:A20,MODE(IF(ISTEXT(A1:A20
),MATCH(A1:A20,A1:A20,0))))

View 9 Replies View RelatedI 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 am creating an excel spread sheet for a project I am doing, I need to create a daily chart for 6 months of water usage that results in averaging set targets.
I have made a chart with the average uses per day but would like to have daily numbers that average out to what i have but in a random sequence e.g. i have that a shower uses 320 litres per day for 2 people is there a way i can make a chart that says: 300 (a1) 340(a2) 260(a3) 360(a4) etc i need to do this for 180 days with random numbers generated to average the same overall. I dont know even how to generate random numbers.
Any way to make say cells A1 thru A10 produce random numbers from 0 to 9.
I would like to do it without a macro if possible. I also need a button to generate those random numbers. I know this button may make it impossible to not use a macro. If it has to be done with a macro then so be it.
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?
