im trying to create a simple random sample from my data set of size n=100 and then i need to repeat that step a 1000 times to make a new data set that i can transfer over to stata. Everything I have seen on the internet involves generating random numbers which isnt what i want. I need to be able to generate a random sample.
Currently my excel spreadsheet consists of 4 columns with 200 entries in each column.
I want to generate random times in excel between upper and lower limits , which i can do , but i also want dates in same cells with out randomization , means dates should act independently and time should randomize
it should be something like that

I want to pull a sample of 15 numbers from column A, the catch is that the contents of column B cannot match once the sample is pulled. How do I do this.
View 9 Replies View RelatedI've coded a macro that can randomly sample out rows of data from a sheet. This macro is used to sample out certain rows from a master sheet full of data (which has 48 columns) based on user names (a column titled LAST_UPDATE_NAME). For Example (ref. wkb attached), if for 5 users named Alastor, Catherine, Emma, Julie and Victor for whom i've to choose data from the Dump sheet.
I need to design a module in which if i input the no. of samples to be chosen against each name, then that many number of rows has to be chosen for that particular name and copied to a new sheet (probably such sheets can be renamed with the usernames). Also i want to consolidate the copied data from the multiple sheets and consolidate them to one sheet.
I am working on a sampling tool in Excel which is based on what a user enters into a column. The user enters observation codes (text) in column A beginning at row 2 and going down to however many they have. I already have formulas which determine the sample size needed based on the number of nonblank values in that column; the resulting sample size is in G4. I'm thinking that I will need to have a form with a button module to select the random sample from the values in col A. This way Excel isn't running the module while the user is entering the values. The resulting sample can be pasted into a separate column or sheet.

No matter how long the column, I only want to pull out the sample date and time 20 times. So if I had data in column A with 300 rows, I want to divide 300 by 20 and pull those 20 numbers and put them in column B in chronological order. Same thing if I had 4000 rows in column A, I only want 20 samples.
View 5 Replies View RelatedI 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 RelatedI have a rand () which provides me a different number upon calculate. I would like to run a loop for 1000 times and take the value and copy and paste in a range.
The below sorta works, but at times it stops or doesn't work at all. I have a loop for the counter and the for each to place the value into the cell and have it run over and over and placing the value in the next cell underneath. I have the counter at 10 so I dont get stuck in some endless loop before I know it works.
Code:
Sub montecarlos()
Dim MCs As Long
Dim c As Range
Dim lCount As Long

lCount = 0
lNum = 1

How do I generate repeat numbers when compared to previous row?
E.g.
Column No A2, B1, C1, D1, E1
Row no... A1 5 12 23 50 3
Row no... A2 10 21 5 25 6
Repeat number for above is 5
Given:
1) 5 cells only. All numbers are integers, no fractions
2) In a row same number is not repeated.
3) It is possible to repeat all numbers in a new run.
In cell A2 I have the date 28/12/11, I need that date to repeat 6 times, then in A8 it should say 01/03/11 6 times and so on , I know this can be done but my brain is on a go slow this afternoon and I can't for the life of me work it out
View 3 Replies View RelatedI 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.
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:
3
9
4
5
1
0
6
8
7
2
Or, they could look like this:
9
7
5
2
8
4.................
I was just wondering if there is a way to make rand or randbetween functions work with text. Alternatively, is there another function that will allow me to do this, without adding numbers in the parallel row.
I want the column, to randomly choose between "male" and "female". I do not want to add additional rows or columns preferably..
Is it possible to use the =randbetween() function to generate a random number between 0.8 and 1.2.

View 9 Replies View Relatedi have worked in access using vba procedures. i can easily create a form in access that generates a random integer number between 0 and 20 and the user will guess the number between 1 to 20 if the random number is 16 and the user enters 14 the program will display a msg box saying too low or too high. here is the code .
Option Explicit
Private Const MAX = 20
Private Const MIN = 1
Private iKey As Integer
Private lTries As Long
Private Function Random() As Integer
Random = CInt(Int((MAX - MIN + 1) * Rnd() + MIN))
End Function
Private Sub cmdGuess_Click()
Dim lGuess As Long
now i have to do the same thing in excel create a program that will ask the user to enter numbers between 0 to 20 and see if the random number and user guess is same or not. but i have never worked in excel using vba procedures how can i achieve the same thing in excel using a vba procedures.
I'm using Excel to generate a userid based upon criteria (e.g. IF column A = 2, and not in array(another sheet), use a random id). This works, but I want an incremental id (whether already used up).
I am using =MAX(IF(LEFT(Users!B1:B19900)="2",Users!B1:B19900)) to get the highest number in the array ...
I have values

I want to generate numbers (1 to 15) in cells A1 through O1, but the
number in each cells should be unique compare to the other cells, how
can I do it? If I use =randbetween(1,15), I can not get unique number
in each cell, some numbers are duplicated.
How do I use RAND to generate random numbers between 0.25 & 0.5?

In addition to data from af directory i got it must be possible to solve some home-made problems. Therefore i need to make a program that can generate new problems in Excel - likely on the same sheet used for the imported problems (another code i got).
It should be possible to specify the size of the problem, in other words the number of cities. Like the problems from the same directory. The problems i am generating have to consist of a number of cities with its x-y-coordinates. It will be useful if the program or the user sets a minimum and maximum value of the allowed x-y values so they are within a certain interval.
Do i need a very big code for this?

I've got a problem with creating random numbers for a fictional portfolio. I've to have a row of random number but they have to add up to 1. Example: Need random numbers from B1-B11

I tried to do it with the solver addin, but it only takes simple numbers as a constraint.
