stats_dens_uniform — Probability density function of the uniform distribution

说明

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

Returns the probability density at x, where the random variable follows the uniform distribution of which the lower bound is a and the upper bound is b.

参数

x: The value at which the probability density is calculated
a: The lower bound of the distribution
b: The upper bound of the distribution

返回值
