Ordinal Alpha

[MIGUEL IPANAQUE]

Good Morning Estimates, I am new with Stata and Forum , I hope you understand me, I'm desperate because I do not know the command for ordinal alpha and get my results. I would appreciate if someone could guide me and help with that. Thanks for your time.

I have a Scale Dimension likert (1 - 5) with 4 items, I got the alpha of cronbach but by what I read the right one to use is the ordinal alpha with a polychoric matrix.

You'll increase your chances of a useful answer if you follow the FAQ on asking questions - provide Stata code in code delimiters, readable Stata output, and sample data using dataex. Do not provide files - most of us will not open them. Also, please do not try to push us to respond more quickly. The volunteers on this listserve do not respond well to being pushed.

The obvious routine is called alpha. The next thing is the google ordinal alpha with a polychoric matrix Stata. You'll find this has been discussed.
