Geometric_Rand

Function Geometric_Rand - Generate random geometrically distributed integers

Calling Sequence  Rand(Geometric(p))
Return Type  integer
Synopsis This function returns a random geometrically distributed integer with average (1-p)/p and variance (1-p)/p^2. In mathematical terms, the probability that the outcome is i is p*(1-p)^i (for 0 <= i). Notice that the distribution starts at 0. Geometric_Rand uses Rand() which can be seeded by either the function SetRand or SetRandSeed.
