icc: Compute the ICC from a lmer (package lme4) model

In dustinfife/flexplot: Graphically Based Data Analysis Using 'flexplot'

Compute the ICC from a lmer (package lme4) model

Description

This function will extract the variances from a mixed model and output the value of the ICC

This function will extract the variances from a mixed model and output the value of the ICC

Usage

icc(model)

icc(model)

Arguments

model

a lmer model

Details

Recall that the equation for the ICC is var(school)/[var(school)+ var(person)]. This forumla extracts the necessary variances from the mixed model and computes it.
