# Sib-pair Command: rand|rnorm

 Class Algebraic operators and function Name rand | rnorm Arguments

Produce a random value from U(0..1) or N(0,1). That is, a double precision number from the uniform distribution between 0 and 1, or from the Normal distribution with mean 0 and variance 1.

Example:

```>> clear
>> set seeds 123 5432 1245
Seeds for RNG (AS183)=   123  5432  1245

>> { rand rand rand }
=>  0.5027132034301758
=>  0.8120918273925781
=>  0.7080494165420532
>> sim ped 100 1 1 1
>> run
>> set loc v1 qua
>> v1=rnorm
>> his v1
