stats_cdf_uniform — Calculates any one parameter of the uniform distribution given values for the others.
$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 number of successes,
the lower bound and the higher bound of the uniform distribution, respectively.
