(PECL stats >= 1.0.0)

stats_dens_gamma — Probability density function of the gamma distribution

说明

stats_dens_gamma ( float $x , float $shape , float $scale ) : float

Returns the probability density at x, where the random variable follows the gamma distribution of which the shape parameter is shape and the scale parameter is scale.

参数

x

The value at which the probability density is calculated

shape

The shape parameter of the distribution

scale

The scale parameter of the distribution

返回值

The probability density at x or FALSE for failure.
