i have a path with a set of continuous variables that predict a categorical variable

for example : (a,b,c continuous and AA categorical)

what are the units of the total effects? are they also odds ratio? what if they are negative? how can they be converted to odds ratio?

maybe it is log odds?

Any regression of AA on a covariate is either a probit or logistic regression depending on the estimator you use. All of the regressions of c ON a covariate are linear regressions.

so if for example:
c on a (a_c)
AA on c (c_AA)
AA on a (a_AA)

model constraint:
new (AA_total)
AA_total = a_c*c_AA + a_AA

would AA_total be a logistic regression coefficient? (given estimator=mlr)

A categorical outcome in a mediation analysis needs special attention - see the article on our website
