Probabilities.UniformCDFInv Function

Uniform distribution point percent function (PPF).

Pascal
function UniformCDFInv(p: double; a: double; b: double): double; overload;
Parameters 
Description 
Probability, real positive value on closed interval [0,1]. 
Distribution parameter, real value, defining distribution lower bound. 
Distribution parameter, real value, defining distribution upper bound. 

the Uniform distribution point percent function (PPF) for probability p using the parameters a and b. The parameter a must be smaller than parameter b and p must lie on the interval [0,1], otherwise the result is NAN.

function UniformCDF(x: single; a, b: single): single; overload;  

The inverse uniform cumulative distribution function is defined by the following equation: 

 

where a and b define the interval on which uniform CDF is defined.
