stats_cdf_uniform

(PECL stats >= 1.0.0)

stats_cdf_uniformCalculates any one parameter of the uniform distribution given values for the others

Descrierea

float stats_cdf_uniform ( float `\$par1` , float `\$par2` , float `\$par3` , int `\$which` )

Returns the cumulative distribution function, its inverse, or one of its parameters, of the uniform distribution. The kind of the return value and parameters (`par1`, `par2`, and `par3`) are determined by `which`.

The following table lists the return value and parameters by `which`. CDF, x, a, and b denotes cumurative distribution function, the value of the random variable, the lower bound and the higher bound of the uniform distribution, respectively.
