Hi, is there a way to estimate an ICC from a frailty model, such as that shown in output 89.11.5 in phreg's documentation Example 89.11 Analysis of Clustered Data. The model has a random effect for subject and proc phreg prints out a covariance paramater estimate. Link to the example below. https://documentation.sas.com/?docsetId=statug&docsetTarget=statug_phreg_examples11.htm&docsetVersion=15.1&locale=en Thanks!

Updated solution ... There are several good comments here, but this SAS note describes a more complete solution to the original problem.

hi i need your help. my one variable is dummy. the variable is latent and has five dimension. each dimension has 5 to 6 items. now i want to do a factoranalysis of that varible to check that these items under each dimension can be taken as it is or remove form the list to make the instrument reliable to measure the variable. and the variable is Corporate social responsibility. the other variable is competition which is meaured through HH index. kindly suggest me to move on..... thanks

Model effect selection for generalized linear models is available beginning in the current release - SAS 9.4 TS1M0 - using PROC HPGENSELECT. For count models, it can also be done using the SELECTVAR= option in PROC COUNTREG in SAS/ETS software. See the documentation: http://support.sas.com/documentation/cdl/en/stathpug/66410/HTML/default/stathpug_hpgenselect_toc.htm http://support.sas.com/documentation/cdl/en/etsug/66100/HTML/default/etsug_countreg_toc.htm

Thank you very much. It makes sense now.
