See stats::Exponential.

Usage

dist_exponential(rate = NULL)

Arguments

rate

Scalar rate parameter, or NULL as a placeholder.

Value

Details

The parameter can be overridden with with_params = list(rate = ...).

x <- d_exp$sample(20, with_params = list(rate = rate))
d_emp <- dist_empirical(x, positive = TRUE)

  empirical = d_emp,
