How to set up the syntax for the model (path analysis) which has both Exogenous categorical variable and Exogenous continuous variables in path analysis for continuous outcome variable (endogenous variable?
There are two types of Exogenous categorical variable: Binary and nominal (1= BA 2= MA C=PHD 4=OTHER)
The model is estimated conditioned on the observed exogenous variables in regression and path analysis. They can be binary or continuous. In both cases, they are treated as continuous. You should create a set of dummy variables for the nominal variable.
Can you explain why Mplus doesn't distinguish between binary or continuous for exogenous variables. I would like to report a correlation table of my path model but am not sure if Pearson's is the appropriate correlation coefficient for the exogenous binary variable included. Would it be ok to report Peason's in a correlation table even though one variable is not continuous? Thank you!
Mplus doesn't distinguish between binary or continuous for exogenous variables because that is not done in regular regression. You can if you like put a binary exog vble on the Categorical list, but that makes an assumption of an underlying normal distribution for this variable which is not necessary. You can present regular Pearson correlations for the binary variables, just being clear that that is what they are. It isn't a perfect summary of the data with categorical variables (raw data is) but it's still informative.
Can we code our binary exogenous indicators as 0,1 or 1,2 is a better way? Also please guide how to ideally code the multinomial ordinal,binomial ordinal and multinominal nominal and binary nominal variables?
