I have a set of data which I divided into a training subset and a validation subset. There is a column called TRAIN with a value of 1 indicating an entry is in the training set. I wish to use only the training data to fit the model. but I wish Mplus to generate factor score for the whole set of data, what is the easiest way of doing so. Currently I have: VARIABLE: USEOBSERVATION = (TRAIN EQ 1) but SAVEDATA: FILE is res.dat ; SAVE = FSCORES; only generate factor scores for the training set. Do I have to setup a new model and manually putting in the factor loadings from this result in a new zero dof CFA to generate factor scores for the validation data? Is there an easier way? |

Yes, you would need to do that. Use the SVALUES option of the OUTPUT command to obtain input with the results as starting values. Change * to @ and use that input and the validation data to generate factor scores for the validation data. |
