eval_property: Evaluate a distribution

In vincenzocoia/distionary: Create and Evaluate Probability Distributions

Evaluate a distribution

Description

Evaluate a distribution property. The distribution itself is first searched for the property, and if it can't be found, will attempt to calculate the property from other entries.

Usage

eval_property(distribution, entry, ...)

Arguments

distribution	Distribution object.
entry	Name of the property, such as "cdf" or "mean". Length 1 character vector.
...	If the property is a function, arguments to the function go here. Need not be named; inserted in the order they appear.

Value

The distribution's property, evaluated. If cannot be evaluated, returns NULL.

Examples

d <- distribution(cdf = \(x) (x > 0) * pmin(x^2, 1), g = 9.81)
eval_property(d, "g")
eval_property(d, "quantile", 1:9 / 10)
eval_property(d, "mean")
eval_property(d, "realise", 10)
eval_property(d, "foofy")
eval_property(d, "foofy", 1:10)
