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
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)
.
