Description

computes the cdf with the lower tail of the non-central beta distribution.

Syntax

double ncbetacdf( const double dX, double a, double b, double lambda, int * nFail = NULL )

Parameters

dX: [intput]value of beta variate. must lie on the interval [0, 1];
a: [input] first shape parameter, a, of the required beta distribtution
b: [input] second shape parameter, b, of the required beta distribtution
lambda: [input] non-centrality parameter of the required beta distribution
nFail: [output] on successful exit, it returns the NAG error code NE_NOERROR; if an error or warning has been detected, then it returns the specific error or warning code.

Return

Returns value of cdf of the Non-central Beta distribution

Examples

EX1

void ncbetacdf_ex1()
{
        double x[]= {0.25, 0.5, 0.75};
        double a = 1.0, b =3, lamda = 10;
        for(int ii = 0; ii<3; ii++)
                printf("%f     %f      %f      %f:     %f\n", x[ii], a, b, lamda, ncbetacdf(x[ii], a, b, lamda));
