The factor analysis model is
x = Lambda f + e

but the major restriction is that the scores be uncorrelated and of unit
variance, and
that the errors be independent with variances Phi, the uniquenesses.

What am I missing? factanal() are supposed to give independent errors vecto
The factanal was called with 'varimax' rotation. The factors scores are
uncorrelated. But
the residuals I got by using
X - sum(loadings*factors-scores) is not uncorrelated to the factor scores.
I thought the residuals should be independent to the factor scores as ?factanal

What did you u
In R factanal output, I can't find a function to give me residuals e.
I mannually got it by using x -lamda1*f1 -lamda2*f2 - ... -lamdan*fn, but the e
I got are not uncorrelated with all the f's.
What did I do wrong? Please help.
