 FTR, The regression procedure does contain an option to save the scores, but it's not that hard to just create a compute statement: compute yhat = -2.4567 + X1 * 0.2348 + X2 * (-2.4500). Or whatever. I don't deny that factor scores can be useful and my understanding is that they are more complex to compute but I have not ever used factor scores because I almost always want to know what a real score is, not a factor score.  That is, if I have a measure and find that items 1, 2, 3, all measure factor 1, I DO NOT want the F1 score (usually), I want the score one those three items, which is also trivial to create: * assume items 1 and 3 are revrse-coded. All variables are on a 5-point likert. compute V1R = 6 - V1. compute V3R = 6 - V3. compute F1 = mean(V1R, V2, V3R)*3. So, your statement that EFA is worthless unless you can save the factor scores is incorrect. -Alan On 1/6/2016 4:35 PM, news wrote: Saving factor scores would be a very welcomed innovation. What is the sense of factor analysis if you can't reuse the scores ? The same is true of regression scores. - ftr On 04/01/2016 21:19, Alan Mead wrote: I don't think PSPP has an option to save factor scores (yet): https://www.gnu.org/software/pspp/manual/html_node/FACTOR.html -Alan On 1/3/2016 9:07 AM, Justo de Jorge Moreno wrote: Dear list I am new to PSPP.
