Struct rand::distributions::normal::LogNormal
[−]
[src]
pub struct LogNormal {
// some fields omitted
}Unstable (
rand): use rand from crates.io
The log-normal distribution ln N(mean, std_dev**2).
If X is log-normal distributed, then ln(X) is N(mean, std_dev**2) distributed.
Methods
impl LogNormal[src]
fn new(mean: f64, std_dev: f64) -> LogNormal
Unstable (
rand): use rand from crates.io
Construct a new LogNormal distribution with the given mean
and standard deviation.
Panics
Panics if std_dev < 0.
