Intuition suggests that altering the covariance structure of a parametric model for repeated-measures data alters the variances of the model's estimated mean parameters. The purpose of this article is ...

Four large-sample methods are proposed for testing the equality of the variances of a p-variate normal population. Two of the methods are asymptotically distribution robust against departures from the ...

For balanced data, the two-way random effects model is estimated using the method of Fuller and Battese (1974), so in this case, the RANTWO option is equivalent to the FULLER option already existing ...
