rvquantile: Componentwise Quantiles of Random Variables

Description

Computes componentwise quantiles of random vectors or arrays.

Usage

rvquantile(x, ...)
  ## S3 method for class 'rv':
rvquantile(x, probs=c(0.025, 0.10, 0.25, 0.50, 0.75, 0.90, 0.975), ignoreInf=FALSE, ...)
  ## S3 method for class 'rvsummary':
rvquantile(x, probs=c(0.025, 0.10, 0.25, 0.50, 0.75, 0.90, 0.975), ...)
  rvmedian(x)

Arguments

x

an object

probs

numeric vector of probabilities with values in [0,1]

ignoreInf

ignore infinite values

...

further arguments passed to quantile

Value

• A numeric vector of quantiles.

Details

rvquantile applies the quantile function to each column of sims(x).

rvmedian applies median to the each column of sims(x).
