Hi,
I�m a German student doing her diploma thesis in Human Resources
Management. I�ve got 2 questions.
1. I would like to do a reliability analysis with Spearman Brown. (I
have already calculated Cronbach�s Alpha). I only found the command
"Spearman�s rank correlation".
Can anybody please help me to get the reliability coeffizient
(Spearman_Brown)
Spearman Brown is a prophecy formula. It predicts what alpha would
be, if you had a different number of items in your scale.
You can read about it in any decent book on psychometrics, and if you
type it into Google, you'll find:

2. How can I use a factor analysis with stata.I dont�t know the command.
It would be very kind if anybody could help me.
