Maybe someone can > tell me if I am correct. many thanks! So your dependent variable is "DEGD" which is a count variable with basically a high number of zeros. Is that correct? If you find a coefficient from the inflation part of the model to be negative then means that per increase in x (the independent variable, however this is scaled, let's assume it's continuous) the chance of having a zero count decreases since you are predicting count=0 vs count>0.
