I’m doing a factor analysis and I get an
ERROR: communality greater than one
What does this mean and can I fix it.
My number of factors is 4 I found this using kaisers criteria but now I’m thinking maybe it’ll work if I have 3 factors please help! Also I’ve done an orthogonal varimax rotation

I can't help directly with a response to your question.

 

You can help someone who knows more about this by providing as a minimum the code that you ran that generated this error.
