Likelihood Ratio Criterion for Mean Structure in the Growth Curve Model with Random Effects

In the present paper, we consider the likelihood ratio criterion (LRC) for mean structure in the growth curve model with random effects. It is difficult to express the LRC as a closed form because of a restriction on parameters. The lower bound and upper bound of the LRC are suggested as a closed form. By using them, it is shown that the least favorable distribution of the LRC isΛ-type distribution.
