- scipy.special.stdtr(df, t) = <ufunc 'stdtr'>¶
Student t distribution cumulative distribution function
Returns the integral from minus infinity to t of the Student t distribution with df > 0 degrees of freedom:
gamma((df+1)/2)/(sqrt(df*pi)*gamma(df/2)) * integral((1+x**2/df)**(-df/2-1/2), x=-inf..t)
