Struct rand::distributions::LogNormal
source · [−]pub struct LogNormal { /* private fields */ }Expand description
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.
Example
use rand::distributions::{LogNormal, Distribution};
// mean 2, standard deviation 3
let log_normal = LogNormal::new(2.0, 3.0);
let v = log_normal.sample(&mut rand::thread_rng());
println!("{} is from an ln N(2, 9) distribution", v)Implementations
