I am using a two-factor ANOVA model with random factor effects including the interaction, i.e. the factors are crossed. I would like to be able to generate all four variance components along with approximate confidence intervals using the NLME package. However, I do not know how to specify the random option because of two problems. First, I do not know how to enter the interaction term into the option. Second, I do not know how to enter in the covariance matrix (see Neter et. al., Applied Linear Statistical Models, 4th ed., page 977). Is there anyone who has confronted this problem before that would be willing to help? Thank you.
