Constructor & Destructor Documentation

plGamma::plGamma (  const plVariablesConjunction &  V, plFloat  a, plFloat  b, plFloat  mu = PL_ZERO )

Constructs a Gamma distribution on the domain of {V}. {a} is the shape parameter (kown as {alpha} or {gamma}). {b} is the scale parameter (known as {beta}). {mu} is the location parameter. If {mu} is not defined, {mu = 0} is used. {a} and {b} must be > 0 and {x} (the variable) must be >= {mu}. The case : {mu = 0, b = 1} gives the standard gamma distribution. Definiton of gamma density: f(x)= (x-mu)^a-1 * exp (-(x-mu)/b) / (b^a * gamma(a))
