Test of variance components of linear mixed model
Song-Gui Wang · 2007
For the linear mixed model which has two variance components,the exact F test and generalized p-value test are obtained when design matrix of random effects is arbitrary.An existence condition of the exact F test is obtained.An sufficient condition under which the exact F test is uniformly most powerful unbiased test is discussed.By Monte Carlo simulation,probability of making type one error and power of test are obtained.The simulation result displays that the generalized p-value test commendably controls the probability of making type one error.
