WitrynaThis function tests for hypothesis H0: L beta R = A, versus Ha: L beta R != A. The beta is estimated by the envelope model with t-distributed errors. If L = Ir, R = Ip and A = 0, then the test is equivalent to the standard F test on if beta = 0. The test statistic used is vec (L beta R - A) hatSigma^-1 vec (L beta R - A)^T, where beta is the ...
