Robust score (Rao) tests with finite-sample correction
robust_score_test.Rd
The default behavior is to do no finite sample correction (for the covariance of the score) for correlated data, but to do it for uncorrelated data. This choice performed best under a small simulation study. See Guo et al for details; the proposed modification is in equation 20.
