Hi all,

I want to draw a random sample [with replacement] of size 10 (suppose

from a population having members : 1, 2, 3, and 4, where I assum

following:

Probability that 1 will be drawn is : 0.1

Probability that 2 will be drawn is : 0.4

Probability that 3 will be drawn is : 0.4

Probability that 4 will be drawn is : 0.1

Can anyone tell me that : is there any VBA function for doing that? I

no, how I can write my own function using VBA?

Thanks and Regards

Here's a non-VBA solution, using nested IF functions and the cumulative

distribution:

Enter =RAND() into a cell, e.g., cell A1.

In another cell, e.g., B1, enter

=IF(A1<=0.1,1,IF(A1<=0.5,2,IF(A1<=0.9,3,4)))

Copy A1:B1 and paste into A2:B10. Press F9 to debug.

Or, download the tryout version of RiskSim from www.treeplan.com, and use

its RANDDISCRETE function.
