ncfcdf
Description
Noncentral F cdf
Syntax
double ncfcdf( const double dF, double df1, double df2, double lambda, int * nFail = NULL )
Parameters
- dF
- [input] deviate from the non-central F-distribution, .
- df1
- [input] degrees of freedom of the numerator variance, . .
- df2
- [input] degrees of freedom of the denominator variance, . .
- lambda
- [input] non-centrality parameter
- 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 Non-central F-distribution cumulative distribution function
Examples
EX1
void ncfcdf_ex1()
{
double x[]= {0.25, 0.5, 0.75};
double df1 = 3, df2 = 2, lamda = 10;
for(int ii = 0; ii<3; ii++)
printf("%f %f %f %f: %f\n", x[ii], df1, df2, lamda, ncfcdf(x[ii], df1, df2, lamda));
}
