P = NCTCDFVW(X,NU,NCP,TAIL) returns the cummulative distribution function (CDF) of the noncentral T distribution with NU degrees of freedom and the non-centrality parameter NCP, at the values X.

NCTCDFVW is suggested for computing extreme tail probabilities of the non-central T distribution with large noncentrality parameter.

The CDF is computed by the GAUSS-KRONOD (non-adaptive) quadrature.

Improved integration limits and precision.


Fixed some minor bugs. Possibility to select different number of sub-intervals for integration.
