MATRUN PFACT,R,k
gives the principal axes solution as factor matrix PFACT.M .
The difference in estimated and computed communalities is displayed
and the computed communalities are placed on the diagonal of R.
MATRUN PFACT,R,k can be reactivated several times until
the process has converged.
The communalities and efficiencies of the factors can be computed
afterwards by MATRUN SUM2,PFACT.M
