Struct sprs_rand::rand::distributions::Exp1 [−][src]
👎 Deprecated since 0.7.0:
moved to rand_distr crate
Samples floating-point numbers according to the exponential distribution,
with rate parameter λ = 1
. This is equivalent to Exp::new(1.0)
or
sampling with -rng.gen::<f64>().ln()
, but faster.
See Exp
for the general exponential distribution.
Implemented via the ZIGNOR variant1 of the Ziggurat method. The exact description in the paper was adjusted to use tables for the exponential distribution rather than normal.
