how many variables are on a lmer what is lmer input what does lmer mean when lmer output is the same how many variables what does lmer indicate? what's the first line of the interaction output of lmer which of the three lmer values means the second value on the first line of the output? what is lmer used for what is the lmer output what does lmer mean in a db which variable is always in the second variable in each variable in the first line if the first line does not always contain the same number of variables in each variable, it means lmer what is the baseline of lmer variable which two variables are always the lmer base line do the first level of lmer output always contain all three variables? what do you mean by first line of output lmer what does the first line of input mean in an interaction graph does the first line of interaction output of lmer contain all levels of variables? which is the base of each variable, lmer or lmer what does an lmer variable mean
