The UCLA HLM site has several examples using the HSB dataset on this page: http://www.ats.ucla.edu/stat/hlm/seminars/hlm_mlm/608/mlm_hlm_seminar_v608.htm

The third model enters SES as a group-mean centered variable at level-1.  HLM output reports a .908 reliability estimate for the intercept and a .260 reliability estimate associated with SES. 

Using the variance components reported for the intercept and the level-1 residual, I’m able to calculate a lambda value for each schoolid (n=160), and then sum across those to obtain an overall reliability estimate that matches the HLM output.  However, I’ve been unable to do similar calculations and arrive at the .260 provided for the SES reliability. 

It's not clear to me how I can obtain the parameter dispersion matrix which would contain both parameter and error dispersion around each Beta.  Essentially, i want to know these two facets about the slope parameter associated with SES.  Is there a way to obtain this using ODS?  Is there something that can be obtained and further processed inside IML?

Any thoughts or insights are greatly appreciated.

What is ANOVA?

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
