I am trying to perform a model 3 ANOVA for a 2 factor (say factor A and
factor B) anova in which factor A is fixed and factor B is random.
Therefore, the error term for the test of factor A should be the A:B
interaction term and the error terms for B and A:B should be the model
residual (within) term. I have tried to work out how to specify such
error strata using aov, however, I have had little success. Is there a
way to specify just the interaction (A:B) as an error term using Error()
within aov or provide a list of error strata.
Ideally as Error=list(A="A:B",B="Within", A:B="Within")
In addition, I have tried using lme to perform this function, but again
without much success.
Can anyone offer any ideas
Ta
Murray
