i have a path with a set of continuous variables that predict a categorical variable for example : (a,b,c continuous and AA categorical) a->c->AA b->c->AA b->AA 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. |

thanks! 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 Muthén, B. & Asparouhov, T. (2015).
