Dear Detlew!

❝ Inspecting it I have some doubts:

❝ ❝ […] some nonsense code

❝

❝ Must the EMA guidance interpreted in this way, i.e. analysing the dataset with 'pseudo' periods and sequences? Or should it interpreted the way which is employed in the Q&A for the replicate design (intra-subject variability of the reference). That means only massacre out the data concerning R2 but retaining the original periods and sequences.

Exactly! Should forget copypasting old code when new ‘knowledge’ became available in the meantime.

❝ ❝ FMMSE     <- summary(FullModel)$sigma^2/FMdf

❝ At least the code for FMMSE has stolen my sleep . According to the help page of lm.summary() "... sigma - the square root of the estimated variance of the random error" and IMHO then the MSE is sigma^2 without the division by the degrees of freedom!

Oh s**t!

❝ Check this out via anova(FullModel)["Residuals","Mean Sq"]==summary(FullModel)$sigma^2 .

❝ Or did I miss sumfink here?

No, no. Sorry!
