Normal distribution — dist_normal • reservr

See stats::Normal.

Usage

dist_normal(mean = NULL, sd = NULL)

Arguments

mean: Scalar mean parameter, or NULL as a placeholder.
sd: Scalar standard deviation parameter, or NULL as a placeholder.

Value

A NormalDistribution object.

Details

Both parameters can be overridden with with_params = list(mean = ..., sd = ...).
