On Combining Exact and Approximative Proceedings for Testing Problems in Unbalanced Mixed Linear Models [PDF]

open access: yes, 2000
A method for constructing approximative tests for arbitrary linear hypotheses on variance components in unbalanced mixed linear models is derived. The idea of cell mean models is used to derive independent and 2-distributed mean squares.
