Get the probability mass function of a nonparametric distribution

Get the probability mass function of a nonparametric distribution

Usage

get_pmf(x, id = NULL)

Arguments

x

A <dist_spec>.

id

Integer; the id of the distribution to use (if x is a composite distribution). If x is a single distribution this is ignored and can be left at its default value of NULL.

Value

The pmf of the distribution

Details

An uncertain (Dirichlet-backed) nonparametric distribution has no concrete PMF, so calling get_pmf() on one is an error. Resolve it to a fixed PMF first with fix_parameters() (e.g. strategy = "mean").

Examples

dist <- discretise(Gamma(shape = 3, rate = 2, max = 10))
get_pmf(dist)
