Hi again d_labes,

❝ ❝ In a mixed model -if that's you case cf above- you have a V where the diagonal is either

❝ ❝ a. s2wT+s2bT or s2wT+s2bT (full repl.)

❝ ❝ b. s2wT or s2wR+s2bR (partial repl.)

❝

❝ :confused:

See below.

❝

❝ I have a V matrix (example subject in sequence TRR, i.e. 2x3x3 design)

❝ s2b+s2wT s2b s2b

❝ s2b s2b+s2wR s2b

❝ s2b s2b s2b+s2wR

❝ where s2b is the common between-subject variance.

Sorry you're right there's something I left out. For T the error is the total var. When equal between's can be assumed for T and R you get s2b+s2wT and not s2wT.
The errors are the withins on the diagonal of V; just take the average to get the mean squared error.

Or did you mean something entirely different?

Btw, shouldn't it be zero in cell (2,1), (3,1), (1,2) and (1,3) ?
I am not sure you'd co-vary a T-observation with an R-observation.
