(1) I fit a 1-factor model to a number of categorical items, say F BY Q1-Q20. (2) I then regress the factor on a covariate, F ON COVAR. (3) I now regress on COVAR after centering it (COVAR - mean). In all three cases the loadings remain quite similar but the thresholds with the uncentered COVAR are shifted considerably by a constant. Is this what one would expect and if so how should we understand (or what should we read to understand) the effect of COVAR scaling. |

This outcome is to be expected since the scales of the thresholds for the indicators depend on the means of the variables predicting the indicators - in this case the factor. In case (1) and (3) the factor has mean zero, while in case (2) the factor mean is a function of the covariate. |

Dear Dr. Muthen, I ran a CFA model with censored indicators (3 below and 2 above). However, in the standardized (STDYX) section of the output, there are only coefficients, but not S.E. or p values. Why is that? And How can I get S.E. and p values for the standardized coefficients (I need to report them in my manuscript)? Thanks! |
