| 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
