Principal Component Analysis and Factor Analysis in Stata

[@marcelolima77]

Dear Ani - I just want to say thanks for this incredible channel and for the website - I used the info extensively during my PhD a few years ago and I always thought I wanted to write and say thanks, so I'm finally doing it here. This is a great example of a 'multiplier effect' contribution to the intellectual community. All the best.

The updated Stata program includes at the end the Barlett's test for sphericity using "factortest". At 22:28 in the video, factor analysis "factor $xlist" uses the default option "pf" for principal factors. Line 62 in the updated Stata program also includes "factor $xlist, pcf" which uses the option "pcf" for principal component factors.
