Collapse nonparametric distributions in a <dist_spec>

Source: R/dist_spec.R
collapse.Rd

[Experimental] This convolves any consecutive nonparametric distributions contained in the <dist_spec>.

Usage

# S3 method for class 'dist_spec'
collapse(x, ...)

Arguments

x

A <dist_spec>

...

ignored

Value

A <dist_spec> where consecutive nonparametric distributions have been convolved

Examples

# A fixed gamma distribution with mean 5 and sd 1.
dist1 <- Gamma(mean = 5, sd = 1, max = 20)

# An uncertain lognormal distribution with mean 3 and sd 2
dist2 <- LogNormal(mean = 3, sd = 2, max = 20)

# The maxf the sum of two distributions
collapse(discretise(dist1 + dist2))
