Dear John,
Thank you for your reply. My data is actually simulated under the model X
= Lambda*F + E.
Since my post, I've simplified the simulation of my data and I still get
the error. This is what I've done since my last post.
I constructed Lambda apriori (so I know exactly which observed var
Dear Lisa,
As I said, I don't have a whole lot of time today. At a quick glance, you
simulation seems straightfoward except for

Why don't the factors have 0 means? I assumethat Phi is a correlation matrix.

Dear Lisa,
There doesn't seem to be anything logically wrong with your model.
I don't have much time today to look into it, but trying different optimizers
in version 2.0-0 of sem, using the correlation matrix in place of the
covariance matrix, and setting the par.size parameter, I was unable t
