QUICKICC: Stata module to compute intraclass correlation and standard error calculation after xtmixed

    () (National Opinion Research Center at the University of Chicago)


quickicc calcuates the intraclass correlation (ICC) after fitting a two-level xtmixed model where the intercept is the only random effect. In addition to calculating the ICC, this program also calculates the standard error of the maximum likelihood large sample ICC.
