R Documentation
Performs likelihood ratio test on random effects of linear mixed effects model.
Description
Returns a data frame with values of Chi square statistics and corresponding
p-values of likelihood ratio tests.
Usage
rand(model, ...)
Arguments
model
linear mixed effects model (lmer object).
...
other potential arguments.
Details
The columns of the data are:
Chisq: The value of the chi square statistics
Chi Df: The degrees of freedom for the test
p.value: The p-value of the likelihood ratio test for the effect
Value
Produces a data frame with LR tests for the random terms.

#import lme4 package and lmerTest package
library(lmerTest)
#lmer model with correlation between intercept and slopes
#in the random part
m <- lmer(Preference ~ sens2+Homesize+(1+sens2|Consumer), data=carrots)
# table with p-values for the random effects
