Abstract
A convenient recursive computational method for repeated measures analysis, provided by McGilchrist and Cullis (1990), has been extended by the authors to heterogeneous error structures and also to the repeated measures model with random coefficients. The approach is outlined briefly in this paper. A computing program for the approach has been written and used to obtain results for simulated data having various error structures. A summary of the results is given. The computing program together with some subroutines is available from the authors.
