rv (version 2.3.5)

rvsample: Draw a Sample from the Simulation Matrix of a Random Variable

Description

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

Usage

rvsample(x, size = 1, jointly = TRUE, reject.na = FALSE)

Arguments

x

an object

size

size of the sample

jointly

return joint simulations and not simulations from each component separately

reject.na

reject each draw that contains an NA

Value

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

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).
