rvar_is_finite: Special value predicates for random variables

In posterior: Tools for Working with Posterior Distributions

Special value predicates for random variables

Description

Compute special value predicates (checking for finite / infinite values, NaN, and NA) on all draws within a random variable, returning a random variable.

Usage

rvar_is_finite(x)

rvar_is_infinite(x)

rvar_is_nan(x)

rvar_is_na(x)

Arguments

x	(rvar) An rvar.

Details

These functions return a new rvar that is the result of applying is.finite(), is.infinite(), is.nan(), or is.na() to every draw in the input random variable.

Value

A logical rvar of the same length as the input.
