rand {lmerTest} | 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
    rand(m)
