It depends on the role these variables play in your model. For example, a
nominal variable like gender can be coded 0,1 and used as an exogeneous
variable (path going from it but no path going to it). There is nothing
special you need to do in this case, and it can be done in AMOS. A nominal
variable like success or failure which is endogenous (has a path leading to
it) can also be coded 0,1 but you would need a program like Mplus that
handles logistic regression to estimate the path coefficient - I don't know
if AMOS can do this. Mplus also handles multinomial logistic regression so
your endogenous variable can also have more than two catgories. Another way
nominal variables can be used is to define different groups in a multi-group
analysis, which AMOS and MPlus can do.
Ordinal endogenous variables are handled in Mplus using ordered logistic
regression - in AMOS you might have to treat them as continuous. Hope this
helps.

Dear all
I have a Path analysis model with nominal and orderinal (Likert) independent
variables. how can i deal deal with these variables in the model?
thanks in advance.
