Information

GenerateVariate

Syntax

GenerateVariate(distribution,g,p1,p2,p3,p4)

Description

This function generates a random variate from the distribution indicated with the integer pararameter "distribution", using the following value correspondence:

• 1 = Constant
• 2 = Bernoulli
• 3 = Discrete Uniform
• 4 = Binomial
• 5 = Geometric
• 6 = Negative Binomial
• 7 = Poisson
• 8 = Uniform
• 9 = Exponential
• 10 = Erlang
• 11 = Gamma
• 12 = Weibull
• 13 = Normal
• 14 = LogNormal
• 15 = Beta
• 16 = Johnson (bounded and unbounded)
• 17 = Triangular
• other value = initalization of the generator (call to initGenerator() function).

Examples

 (u,g) := GenerateVariate(2,g,0.4);
 // Generates a discrete variate (u) with Bernoulli(0.4) probability distribution.

 (u,g) := GenerateVariate(11,g,0.4,0.6);
 // Generates a continuous variate (u) with Gamma(0.4,0.6) probability distribution.

The example VariatesSimple2 uses of this function.
