Re: Random Number Generators in SAS

A quick overview of the random number functions is here: Using Random-Number Functions and CALL Routines

Links to the documentation of the different functions can be found in the navigation pane.

Basically, each function provides its own algorithm, and it is up to the user which function (and therefore algorithm) she employs.

Re: Random Number Generators in SAS

You should post it at IML forum.

I remembered Rick said before.

Old rand function like : ranuni(), rannor()....  are using linear congruential generator.

while the new rand function RAND()  is using Mersenne twister.

Re: Random Number Generators in SAS

data rd_numbers;

  random_number = ranuni(0);  /* 0-1 random numbers. you can use these numbers to generate normal or other distribution */

  output;

run;

 

proc univarite data = rd_number; var random_number ; run;

data rd;
do i = 1 to 1000;
x=rand('NORMAL',10,2.3);
output;
end;
run;

proc univariate data = rd; var x; run;
