In a simple longitudinal linear model with two variance-covariance components are compared via simulations the characteristics of the exact likelihood ratio test and characteristics of some (asymptotic) approximations of this test. Comparisons are made for small sample size settings. The asymptotic \(\chi ^2\) approximation seems to be quite adequate.
