Dummy Variables PreviousNext

Dear Dr. Muthen,

I am hoping to run an analysis with a categorical variable as a predictor variable. The variable named (BLA) has five categories 1= Innovators, 2= Early Adopters, 3= Early Majority, 4= Late Majority and 5= Laggards.

In the MPlus syntax BLA is in the variables list and in the used variable list.

What I am not sure is if I create dummy variables for the different categories where do the dummy variables go in the variable list and the used variable list or somewhere else?

How does Mplus know that BLA has the dummy variables associated with it?

Best Regards,

The variable BLA should appear in the NAMES= list because this list refers to the columns in your data set. You can use the Define command to create the 4 dummy variables and they should then appear in the USEV list (not BLA).

Dr Muthen,

Thank you very much for your prompt response!

I need to know how to code the dummy variables correctly for the MPlus syntax?

Best Regards,

Just like you would do in a regular regression. If unclear, consult SEMNET.
