Why aov() with Error() gives three strata?
...sing, then this can be interpreted using random effects as above, with variances of each component proportional to the successive differences. (All assuming that you have a balanced data layout, otherwise aov() is just the wrong tool.) -pd > On 28 Dec 2017, at 19:36 , Jorge Fernando Saraiva de Menezes <jorgefernandosaraiva at gmail.com> wrote: > > Bert, thanks for the reply but I feel that my question is less about > statistics and more about R interface.
