Pearson5Gen(RandomStream s,
double alpha)
Creates a Pearson5 random variate generator with parameters α = alpha and β = 1, using stream s. |
|
Pearson5Gen(RandomStream s,
double alpha,
double beta)
Creates a Pearson5 random variate generator with parameters α = alpha and β = beta, using stream s. |
