ncbetacdf
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));
}
