What is the best way of analyzing DOE data with zero inflated dependent variable? Is it ok to use the zero inflated models ie ZIP, ZAP, ZINB etc.?

We are working with experimental data in which the dependent variable of interest (is count) has a lot of zeros and some few 1's across the treatments under investigation. we therefore need direction on the best way of analyzing the data aside the classical ANOVA technique.

The original DOE was setup in anticipation of observing some counts for the response variable, however, your question suggests you ended up with dichotomous outcome for the response variable. I propose you redefine the response variable and apply modelling techniques applicable for dv with dichotomous outcomes.
