distributional (version 0.2.1)

dist_transformed: Modify a distribution with a transformation

Description

experimental

Usage

dist_transformed(dist, transform, inverse)

Arguments

dist

A univariate distribution vector.

transform

A function used to transform the distribution. This transformation should be monotonic over appropriate domain.

inverse

The inverse of the transform function.

Details

The density(), mean(), and variance() methods are approximate as they are based on numerical derivatives.

Examples

# NOT RUN {
# Create a log normal distribution
dist <- dist_transformed(dist_normal(0, 0.5), exp, log)
density(dist, 1) # dlnorm(1, 0, 0.5)
cdf(dist, 4) # plnorm(4, 0, 0.5)
quantile(dist, 0.1) # qlnorm(0.1, 0, 0.5)
generate(dist, 10) # rlnorm(10, 0, 0.5)

# }
