brede_cdf_t

PURPOSE ^

brede_cdf_t - Student t distribution

SYNOPSIS ^

function P = brede_cdf_t(x, r, my, Sigma2)

DESCRIPTION ^

 brede_cdf_t         - Student t distribution

       function P = brede_cdf_t(x,r, my, Sigma2)

       Input:  x      Value where the function is evaluated
               r      Degrees of freedom
               my     Mean
               Sigma2 Variance

       Output: P   Lower tail area

       Lower tail (cumulated) Student t distribution computed via the 
       incomplete Beta function. 

       The 'x' input can be a vector.

       If the degrees of freedom is zero or less then NaN is returned
       as the lower tail area.

       Example:
         brede_cdf_t(1.8125, 10)
