I am using
lmerTestto run linear mixed models (LMM) to get the p-values. However, in the articles I have written, they will show both
lmerTest. Then I am not sure if I also have cite
lme4when I use only
lmerTestto run LMM models.
Do you have any idea about this?
lmerTest basically offers a bunch of convenience functions on top of lme4. The actual important software is lme4, which implements the model framework. You should definitely give the reference for lme4 as specified in
Douglas Bates, Martin Maechler, Ben Bolker and Steven Walker (2014).
lme4: Linear mixed-effects models using Eigen and S4. R package
version 1.0-6. http://CRAN.R-project.org/package=lme4
This is not only important for giving well deserved attribution, but also to state the lme4 version number.
