Hi Dr. Muthen, I am trying to run a regression model with both binary and continuous predictors in the same model. Can I read the STDY output to get the estimates of the binary predictors and the STDYX output for the estimates of continuous predictors OR is there another way to get the estimates of binary and continuous predictors? Thank you, Sakshi 


You should use StdY for binary predictors and StdYX for continuous predictors. 


Thank you for responding so quickly. I just want to make sure that I understand what you mean. 1) Are you suggesting that in the final output that's generated, I read the StdY output for binary predictors and StdYX output for continuous predictors OR 2) Is there any way to specify in the syntax that I need Stdy for binary predictors and StdYX for continuous? In my model I have X1 = Gender (binary) X2 = Race (binary) X3 = SES (continuous) X4 = Diversity (continuous) My Model statement looks like: Y1 ON X1 X2 X3 X4; Y2 ON X1 X2 X3 X4; Y3 ON X1 X2 X3 X4; Y4 ON X1 X2 X3 X4; Y5 ON X1 X2 X3 X4; and in the output I mention: OUTPUT: standardized; Where in this syntax can I indicate that I need Stdy for binary predictors and StdYX for continuous. I apologize in advance if I sound naive. Thank you 


1) 2) No, you have to pick from different parts of the output. 


I meant to say 1) Yes. 


Okay. Thank you once again! 


Dear Linda, dear Bengt, we are conducting linear regression analyses (no mediators) with ML estimation. We are requesting stdyxstandardization as well as stdystandardization in the outputcommand, but regression coefficients for stdyx and stdy are identical. The formulas for stdyx and stdy provided in the User's Guide are: StdYX = b*SD(x)/SD(y) StdY = b/SD(y); After using these formulas to calculate stdyx and stdy manually, we detected that the coefficients for both stdyx and stdy in the MPlusoutput refer to the stdyxformula. The stdycoefficients that we calculated manually differ distinctively from the stdycoefficients in the MPlusoutput. This problem is occuring in MPlus v8.0 and in MPlus v8.1. Do you have any advice why stdyx and stdycoefficients are the same? Thank you very much and best regards, Matthias Lühr 


Perhaps your x's have been brought into the model by mentioning their variances. If this doesn't help, send your output to Support along with your license number.
