Hi,

In running a EFA in version 6.12, I'm getting this error:

NO CONVERGENCE IN ROTATION ALGORITHM. NUMBER OF ITERATIONS EXCEEDED.
PROBLEM OCCURRED IN EXPLORATORY FACTOR ANALYSIS WITH 3 FACTOR(S).
THE PROBLEM IS PROBABLY DUE TO THE NEGATIVE RESIDUAL VARIANCE FOR
VARIABLE CU.

I see that the maximum number of iterations is set at 10,000. Is it possible to increase this number? If this issue has been addressed elsewhere, please direct me there.

Thanks for any help you may give,

Ann

You can increase the number of rotation iterations using the RITERATIONS option.

Check first if the residual variance of CU is negative. If it is, the model is inadmissible.
