scipy.special.nctdtridf#

scipy.special.nctdtridf(p, nc, t, out=None) = <ufunc 'nctdtridf'>#

Calculate degrees of freedom for non-central t distribution.

See nctdtr for more details.

Parameters
parray_like

CDF values, in range (0, 1].

ncarray_like

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

tarray_like

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

outndarray, optional

Optional output array for the function results

Returns
cdfscalar or ndarray

The calculated CDF. If all inputs are scalar, the return will be a float. Otherwise, it will be an array.
