Hi,
I have the following model which I'm trying to run. Its a fairly simple SEM that's running well, but however the variable conscript_office is categorical (with 5 categories). Mplus now seems to treat it as a continuous variable as I get just one estimate for the regression between systolic blood pressure (syst) and conscript_office.
How do I specify that conscript office is indeed a categorical variable with 5 categories? And do I need to change the model command as well?
MODEL:
syst on bmi;
syst on bwtgestage_sd;
syst on education;
syst on conscript_office;
syst on age;
bmi on bwtgestage_sd;
bmi on education;
bmi on conscript_office;
bmi on age;
bwtgestage_sd on education;
Thanks,
/Amal. |

| Conscript_office is a covariate. Covariates can be binary or continous and in both cases they are treated as continuous. If conscript_office is nominal, you need to create a set of dummy variables. If it is ordinal, you can leave it as it or create a set of dummy variables. |
