statistics: x = ncx2inv (p, df, delta)

Inverse of the non-central T cumulative distribution function (iCDF).

x = nctinv (p, df, delta) returns the inverse of the noncentral T cdf with df degrees of freedom and noncentrality parameter delta, at the probabilities of p.

The size of x is the common size of df and delta. A scalar input functions as a constant matrix of the same size as the other inputs.

nctinv uses Newton’s method to converge to the solution.
