- mqr.spc.util.d2_integral(n, **quad_kws)#
Numerical integration to calculate the d2 unbiasing constant.
Evaluates:
\[d_2(n) = \int_{-\infty}^{\infty} f_2(x; n) dx \]where
\[f_2(x; n) = 1 - (1 - \Phi(x))^n - \Phi(x)^n .\]- Parameters:
- nint
Sample size.
- **quad_kws
Keyword args passed as **quad_kws to
