Hello, how does one use factanal to produce factor scores for a new data set? I have a factor solution estimated from historical data. I have a 'new' data set I just like to create factor scores using the prior estimated factor model. I see a reference to a package tsfa, for time series factor analysis that has a predict function, but like to use the factanal function. Is there an equivalent to predict for the factanal function, i can say newdata="" and extract the scores? [[alternative HTML version deleted]]
