Factanal and MLE

[Moshe Adrian <Moshe.Adrian@morganstanley.com>]

Dear all,

When S-Plus performs factor analysis (maximum likelihood estimate), how
does it choose the factors?  The factors are not unique since you can
rotate the factors via an orthogonal matrix.  So, if solutions are not
unique, how does S-plus choose the solutions it spits out?

Sincerely,

Moshe
