Description

Draws a sample of desired size from each component of a given random variable x.

Usage

  rvsample(x, size=1, prob=NULL)

Arguments

x an object
size size of the sample
prob optional probability vector, usually not needed

Details

Samples (with replacement) from the distribution of the random variable object. In effect it samples from the rows of the simulation matrix sims(x).

Value

A numeric array of dimensions size times length(x).
