scipy.special.stdtridf — SciPy v1.15.2 Manual (original) (raw)

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

Inverse of stdtr vs df

Returns the argument df such that stdtr(df, t) is equal to p.

Parameters:

parray_like

Probability

tarray_like

Upper bound of the integral

outndarray, optional

Optional output array for the function results

Returns:

dfscalar or ndarray

Value of df such that stdtr(df, t) == p

Examples

Compute the student t cumulative distribution function for one parameter set.

from scipy.special import stdtr, stdtridf df, x = 5, 2 cdf_value = stdtr(df, x) cdf_value 0.9490302605850709

Verify that stdtridf recovers the original value for df given the CDF value and x.

stdtridf(cdf_value, x) 5.0
