I'm trying to write a code that will generate random numbers and no number appears more than onece.
For I = 0 To 3
For J = 0 To I
Do
n = Int(4 * Rnd) + 1 'random number generated
Array1(I) = n 'random number settled in an array
If (I = I - J) Then 'checking for the same place in array
numsOK = True
Else
If Array1(I) = Array1(I - J) Then ' comparing two different places in an array
numsOK = False
Else
numsOK = True
End If
End If
I attempting to create a formula that will create random numbers in a column without repeats. For example, I have a spreadsheet with two columns. The first column I want to contain the random numbers and the second column will contain names. I just need the formula to create the random numbers once.
I have three columns A,B&C In the column A Iwill generate random numbers between 40&50, In the Column B I will generate random numbers between 35&45, The column C is the sum of Column A&B(i.e. C=A+B) but I the sum should be between 83&88. I need acondition such that the random numbers generated in Column A&B Should satisfy the Column C(A+B) condition sdatisfying the A&B columns condition.
I get the following error whenever I try running a Monte Carlo simulation with iterations in excess of 64000 (The MC simulation calls the 'NormSInv' worksheet function at least once per iteration, and the argument to the 'NormSInv' function is always a standard normal RANDOM number also generated by Excel VBA): Run-time error '1004': Unable to get the NormSInv property of the WorksheetFunction class Why do I inevitably encounter this error ONLY when the number of iterations exceeds 64000, for instance? Simulations with iterations < 64000 run smoothly without a glitch.
I understand how RAND and RANDBETWEEN work, but have a slightly more complicated random number generation problem that requires a number that isn't solely between two numbers.
I have one cell that is randomly generating a number between 0 and 350 (we'll call this value A) and another randomly generating a number between 0 and 15 (value B). Then, I have a third cell (value C) that equals 15 minus B. Where I am having trouble is with a fourth cell (value D). This cell I want to have randomly generate a number between 0 and 350 but it needs to be D less than the value in A or C more than the value in A. Is there an advanced random number generation technique that can solve this?
Been trying to think of a way to get random numbers 1 to 36 generated without repeating in the same column, however also getting it to perform the same opertaion in 9 more columns (B:J) without the same number appearing in the same row.
example
1 2 5 4 2 5 3 1 3 4 1 5 4 1 2 3 5 3 4 2
Unsure if this is possible, have created a basic script for random number generation but have no clue how to expand across columns.
I would like to generate a random value using a skewed normal distribution. For inputs I have the sample mean, standard deviation, and skewness. I would like to find a way to generate numbers randomly that would fit the skewed normal distribution described by the inputs.
Some information about skewed normal distributions can be found here: ...
But i want to save the number in a dim single variable called N. I try to put N where i have write ActiveSheet.Range("$B$2") and do N=Application.Run ... But it doesn't work.
So i need a way to find the minimum number in a given set of numbers without there being multiple minimums. For example if you had 1,2,3,4,5,6,7 the minimum would be 1. If however you had 1, 1, 2, 3, 4, 5....i want excel to recognize there are multiple minimums (two 1's) and produce a warning (i realize this probably needs to be coupled with an if statement).
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.
I need to generate 8 (random) numbers which should range between 0 to 80 and the sum of those generated 8 numbers should be 80.? How can I achieve this.
I have a list numbered 0 to 300. What I am looking for is a formula to randomly select 150 unique sets of two numbers and list them in separate columns for a competition draw and should appear as per the example below
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.
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?
I am trying to generate random numbers between 0 - 9 in ten cells that do not repeat an always include every value 0 - 9 (0, 1, 2, 3, 4,...9). The object is to have the numbers randomize each time. So cells A1:A10 could look like this:
I have two rows in a sheet with random numbers (1 till 90).
Those numbers in those two rows I change them every 5 minutes with new one still from 1 to 90 I need a "way", in one side of my sheet (lets say in column B) to count how many times a number was repeated after finish my work (example after 2 hour's)
I'm trying to generate random numbers that will add up to a certain number and am having trouble brainstorming how to do so. For example, I'm trying to get a+b+c=6 with a, b, and c randomly generated to add up to 6.
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, but If it has to be done with a macro then so be it.
