I'm trying to do multilevel modeling according to the procedure outlined by your 1994 article and am having some difficulties.
There's 2 main problems. First off, there's always a fixed factor loading of 1.0 in the CFA and the MCFA. Is this required in order to converge on a solution? Is there a way to not have a fixed factor loading?
Also, for the covariance CFA I keep getting an error message that my NOBSERVATIONS exceeds the number in the data. I've tried the N of the individuals as well as the N of the groups. I've also tried going down to as low as 1, and am still getting this message.
Any suggestions?
Thank you

For model identification, one factor loading or the factor variance must be fixed at one.
