stats_rand_gen_beta

(PECL stats >= 1.0.0)

stats_rand_gen_betaGenerates a random deviate from the beta distribution

说明

stats_rand_gen_beta ( float $a , float $b ) : float

Returns a random deviate from the beta distribution with parameters A and B. The density of the beta is x^(a-1) * (1-x)^(b-1) / B(a,b) for 0 < x <. Method R. C. H. Cheng.

参数

a

The shape parameter of the beta distribution

b

The shape parameter of the beta distribution

返回值

A random deviate
