In my research model the independent variables have questions Likert scale , while the dependent variables are dichotomous questions; with PLS Can I combine these types of questions?
Dear Carlos,
You can, but usually when the dependent variable is dichotomic we allpy logistic regression.
I think you want to aplly PLSbecasuse you have a small sample or you have no teory to support your hypotheses. becasuse if it is not this reasion, it will be better to usae SEm, instead of PLS.
Have a nice time

Hi Carlos,
Hair et al. (2014) suggest that the PLS-SEM algorithm works well with binary coded data that are used as a means of categorical control variables or moderators in PLS-SEM models. They further suggest that one should be cautious with the use of categorical (i.e., dummy-coded) scaled data in PLS models as they do have certain limitations.
Hope that helps.
Kevin
