# scipy.special.nctdtridf

`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.
