However, in many scenarios, this assumption does not hold since many factors such as illumination conditions and intrinsic variability of the …

Nettet19. okt. 2024 · Introduction. With mixed models, it is easy to run into data that is larger in size than some more typical data scenarios. Consider a cross-sectional data set with 200 individuals. This is fairly small data. Now, if we observe them each five times, as in a longitudinal setting, we suddenly have 1000 observations. NettetWe introduce an R package, robustlmm, to robustly fit linear mixed-effects models using the Robust Scoring Equations estimator. The package’s functions and methods are designed to closely equal those offered by lme4, the R package that implements classic linear mixed-effects model estimation in R. The robust estimation method in robustlmm
