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
