UNU.RAN transformend density rejection generator

Description

UNU.RAN random variate generator for continuous multivariate distributions with given probability density function (PDF). It is based on the Hit-and-Run algorithm in combinaton with the Ratio-of-Uniforms method (HITRO).

[ Deprecated. Use hitro.new instead. ]

Usage

urhitro(n, dim=1, pdf, mode=NULL, center=NULL, ll=NULL, ur=NULL, thinning=1, burnin = 0, ...)

Arguments

n size of required sample.
dim number of dimensions of the distribution. (integer)
pdf probability density function. (R function)
mode location of the mode – optional. (numeric vector)
center point in “typical” region of distribution, e.g. the approximate location of the mode. If omitted the mode is implicitly used. If the mode is not given either, the origin is used. (numeric vector – optional)
ll,ur lower left and upper right vertex of a rectangular domain of the pdf. The domain is only set if both vertices are not NULL. Otherwise, the domain is unbounded by default. (numeric vectors)
thinning thinning factor. (positive integer)
burnin lenght of burin-in phase. (positive integer)
... (optional) arguments for pdf

This method is deprecated. Please use hitro.new together with ur instead.
