Using real-data examples and by providing tons of output, the authors accomplish to make clear the necessity of the more complex models and thereby invite the reader to invest time for the more fundamental aspects of multilevel analysis. All posts are linked to the chapters from the R-Project manual on this site. The manual is free to use, for it is paid by the advertisements, but please refer to it in your work inspired by it. Feedback and topic requests are highly appreciated. I really like the book as it offers a thorough discussion of the linear and non-linear mixed effects models BTW: not multilevel models, Doug Bates mentioned that issue in Dortmund ;-.

But chapter 2 is really hard stuff, especially for a non-statistician. Ah, thanks for the comment. I always thought these terms were used rather interchangeably.

Perhaps you can elaborate? This is not true. The plate and sample factors in fm2 are crossed. They do not represent levels in a hierarchy. Ah yes, that makes sense.

However, taking a more strict understanding of the term is much more clear. Defaults to "ML".
The default action na. Defaults to an empty list. If TRUE information on the evolution of the iterative algorithm is printed. Generic functions such as print , plot and summary have methods to show the results of the fit. See nlmeObject for the components of the fit.
The functions resid , coef , fitted , fixed. The function does not do any scaling internally: the optimization will work best when the response is scaled so its variance is of the order of one. The model formulation and computational methods are described in Lindstrom, M.edutoursport.com/libraries/2019-11-28/3373.php
R-Sessions 25: Book – Mixed Effects Models in S and S-PLUS (Pinheiro & Bates, 2000)
The variance-covariance parametrizations are described in Pinheiro, J. The different correlation structures available for the correlation argument are described in Box, G. The use of variance functions for linear and nonlinear mixed effects models is presented in detail in Davidian, M. Box, G. Davidian, M. Laird, N. Littel, R.
