Null Distribution

Sometimes it's convenient to work with a distribution object that is akin to a missing value. This is especially true when programmatically outputting distributions, such as when a distribution fails to fit to data. This function makes such a distribution object. It always evaluates to NA.

Usage

dst_null()

Value

A Null distribution.

Examples

x <- dst_null()
mean(x)
#> [1] NA
eval_pmf(x, at = 1:10)
#>  [1] NA NA NA NA NA NA NA NA NA NA
