How to calculate composite reliability (CR) in Stata?

[Frank Flieger]

Hi, Composite reliability (CR) is a common reliability measure to validate a survey construct. There is supposedly a program called "avecr" available that does it https://github.com/franksun319/AVECR but no command on how to install or use it. The "condisc" command only gives average variance extracted (AVE) Does anyone know how to compute CR in Stata?

You can download the do-file from the site that you refer to, it is called avecr.do (or you can copy the text from the site and paste it to a do-file. Then run your sem-command:

webuse bg2, clear
sem Lat -> bg2cost1-bg2cost6

Then run the do-file, avecr.do and type:

avecr Lat
