Random effects contain crucial information to understand the variability of the processes under study in mixed-effects models with crossed random effects (MEMs-CR). Given that model selection makes all-or-nothing decisions regarding to the inclusion of model parameters, we evaluated if model a...

I would like to run a crossed-effects model using xtmixed. Further, I would like this model to have random coefficients in addition to the random intercepts it normally produces. For example, a basic crossed-effects model looks like xtmixed depvar indepvar || _all: R.groupvar1 || group...
(2007), for instance, does not discuss models with crossed random effects, although it clearly distinguishes between nested and crossed random effects, and advises the reader to make use of the lmer() function in R, the software (developed by the third author) that we introduce in the ...
Random effects designA modification of balanced model equations is proposed for constructing confidence intervals on variance components in an unbalanced two-factor crossed random model with interaction.The modification is based on the unweighted sums of squares.Computer simulation is used to demonstrate ...

Most importantly, however, such therapist effects are not considered as effects that have to be eliminated. Rather, the longitudinal, multilevel design allows us to estimate therapist effects in parallel to the implementation effects [5]. Participants (1)Inclusion/exclusion criteria: Participants will...
Active light-emitting components are integrated into a thin flexible plastic-wrap like film to provide an exceptionally large continuous display in which the film contains densely distributed light emitting elements addressed by a grid of transparent conductors. Inexpensive bulk processing techniques are us...
