Dear Listers:
I used cronbach{psy} to evaluate the internal consistency and some set
of variables gave me alpha=-1.1003, while other, alpha=-0.2;
alpha=0.89; and so on. I am interested in knowing how to interpret
1. negative value
2. negative value less than -1.
I also want to re-mention my previous question about how to evaluate
the consistency of a set of variables and about the total correlation
(my 2 cent to answer the question). Is there any function in R to do
that?
Thank you very much!
