Happy Monday to all. There is a new module, -omega-, now available on the SSC, that calculates the ω reliability coefficient in a single command. ω is similar but preferable to Cronbach's alpha because Cronbach's alpha has many statistical assumptions that are rarely met in practice. The literature has been encouraging a move toward ω as the primary reliability coefficient and now it's easy to use in Stata. I hope you find it helpful and please let me know if you find a bug.

Cheers,
