Comparing RESIDUAL and TECH10 

Message/Author 


I've been running a lot of ordinal mixture CFA recently. The OUTPUT RESIDUAL option generates one and twoway marginals with predicted probabilities and standardized zscores. TECH10 also generates this but the two sets of outputs don't appear to be the same. (1) TECH10 seems to generate marginals not stratified on the classes? Is this correct? I saw elsewhere the formula used for the standardized residuals and have been able to replicate them closely. (2) How are the standardized residuals computed by RESIDUAL, which are broken out by latent classes? I can't seem to replicate them, even accounting for rounding error from only having three decimal places. 


(1) Yes (2) sqrt(Nk)*Residual/sqrt(Estimated*(1Estimated)), where Nk is the number of observations in class k picked up from this output section FINAL CLASS COUNTS AND PROPORTIONS FOR THE LATENT CLASSES BASED ON ESTIMATED POSTERIOR PROBABILITIES
