stats_dens_beta — Probability density function of the beta distribution

˵��

stats_dens_beta ( float $x , float $a , float $b ) : float

Returns the probability density at x, where the random variable follows the beta distribution of which the shape parameters are a and b.

����

x

The value at which the probability density is calculated

a

The shape parameter of the distribution

b

The shape parameter of the distribution

����ֵ

The probability density at x or FALSE for failure.
