Modeling the residual structure in a repeated measure design - better, but not still there about gamlj HOT 5 OPEN

What other options would you suggest?

Thanks for swift reply!

There are a number of important residual structures highlighted in the literature. The choice and relevance depend on the research field. See, e.g., Wolfinger (1996) and Heck and Thomas (2022).

Personally, I misses the ARMA, ARH(1) and CSH options, i.e., autoregressive moving average, heterogeneous autogressive, and heterogeneous compound symmetry.

That's doable, the only issue is to let the user to chose from the interface the parameters of the matrix, such as the p and q for ARMA. I'll work on it, thanks

Fantastic - and thanks for your dedication to the development of Jamovi. I look forward to test it :-)

NB. In the current version, I am not sure whether jamovi order the data correctly when using the AR(1) option. Clearly, the data need to be ordered in the correct time sequence for a meaningful estimation. This is unimportant if the level 2 cluster is a group such as a school class or a team.

Best,

we use the default ordering, which corresponds to using the order of the observations in the data. So it is up to the user to order the "time" variable is the correct way.
