Check if a <dist_spec> is constrained, i.e. has a finite maximum or nonzero tolerance.

Description

Usage

## S3 method for class 'dist_spec'
is_constrained(x, ...)

Arguments

x	A ⁠<dist_spec>⁠
...	ignored

Value

Logical; TRUE if x is constrained

Examples

# A fixed gamma distribution with mean 5 and sd 1.
dist1 <- Gamma(mean = 5, sd = 1, max = 20)

# An uncertain lognormal distribution with mean 3 and sd 2
dist2 <- LogNormal(mean = Normal(3, 0.5), sd = Normal(2, 0.5), max = 20)

# both distributions are constrained and therefore so is the sum
is_constrained(dist1 + dist2)
