scipy.special.nctdtridf(p, nc, t) = <ufunc 'nctdtridf'>

Calculate degrees of freedom for non-central t distribution.

See nctdtr for more details.

Parameters:
p : array_like

CDF values, in range (0, 1].

nc : array_like

Noncentrality parameter. Should be in range (-1e6, 1e6).

t : array_like

Quantiles, i.e. the upper limit of integration.
