Convert a distribution's parameters to its natural parameters (per-type)

Per-type conversion of a distribution's parameters to its natural parameters. Dispatched on the distribution type; each method reads the parameter means from ux and returns the natural parameters as a named list (see e.g. to_natural.gamma). The shared pre- and post-processing lives in convert_to_natural(), which computes ux once and passes it in.

Usage

to_natural(x, ux)

Arguments

x

A single <dist_spec>.

ux

The parameter means, as returned by lapply(x$parameters, mean).

Value

A named list of natural parameters.
