stats_dens_cauchy — Probability density function of the Cauchy distribution

说明

float stats_dens_cauchy ( float $x , float $ave , float $stdev )

Returns the probability density at x, where the random variable follows the Cauchy distribution whose location and scale are ave and stdev, respectively.

参数

x: The value at which the probability density is calculated
ave: The location parameter of the distribution
stdev: The scale parameter of the distribution

返回值

The probability density at x or FALSE for failure.
