Q re Linear Models
...bles ("SelfAssessment", "Usefulness",
"Information" and "Ease") that I'd like to include as covariates. These
of course may partially depend on the subject. Additionally, in a
post-test I measure yet another continuous variable for each subject
("UMLTTL").
The problem I have is that I'm not sure how to properly include these
continuous covariates in the groupedData formulas and the lme formulas.
Any help will be appreciated, either on the list of by email.
Many many thanks in advance.
Joerg
