Hi All,
I'm wondering if anyone out there has put together SAS code or macro for the calculation of ICC when dealing with count data in a multilevel framework? This brief paper below appears to outline several different methods that ICCs and VPCs can be obtained, i guess i would be surprised if someone out there hasn't already made this available in SAS.

I have student data nested within schools, where my outcome variable is a count of the number of suspensions accumulated for a given school year. Thus, for about 80% of the students in the file, the value is 0. Any ideas or recommendations on (a) how to analyze the data and (b) how to arrive at an ICC value are greatly appreciated.
