Struct sprs_rand::rand_distr::LogNormal [−][src]
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_distr::{LogNormal, Distribution}; // mean 2, standard deviation 3 let log_normal = LogNormal::new(2.0, 3.0).unwrap(); let v = log_normal.sample(&mut rand::thread_rng()); println!("{} is from an ln N(2, 9) distribution", v)
