Random variables are useful for modeling uncertainty in a system. Unlike regular variable, which are defined by (deterministic) values, random variables are defined by distributions. Rave supports the use of random variables through various sampling (Monte Carlo) based approaches. The main ways to use random variables in Rave are:

[[Random variables]] are useful for modeling uncertainty in a system. Unlike regular variable, which are defined by (deterministic) values, [[random variables]] are defined by distributions. Rave supports the use of [[random variables]] through various sampling (Monte Carlo) based approaches. The main ways to use [[random variables]] in Rave are:
*Declare a variable to be random, in which case it is treated as being random for all purposes in Rave.
*Declare a variable to be random, in which case it is treated as being random for all purposes in Rave.

*Sample data according to random distributions. This lets you generate a data set that involves randomness, but Rave otherwise treats this data as if it were a deterministic sampling.
