random

public DblMatrix random(int nn)

Description copied from class: ProbabilityDensity

Return N random draws from this distribution. This default implementation uses the inversion method which may give suboptimal results.

Overrides:

random in class ProbabilityDensity

hasSupport

public DblMatrix hasSupport(DblMatrix X)

Description copied from class: ProbabilityDensity

Returns 1 if the density has the input value in its support set (domain) and 0 otherwise.
