Student distribution point percent function (PPF).

Syntax
C#
Visual Basic
public static double StudentCDFInv(double p, int Nu);
Parameters
Parameters 
Description 
double p 
Probability, real positive value on closed interval [0,1]. 
int Nu 
Defines distribution degrees of freedom, positive integer. 
Returns

the Student distribution point percent function (PPF) for probability p using the integer parameter Nu (degrees of freedom). Parameter Nu must be positive integer number and probability p must lie on the interval [0,1], otherwise the result is NAN.

Remarks

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

 

The result of StudentCDFInv is the solution of the integral equation of the StudentCDF with parameter Nu where you must specify the probability p.
