Query about Zero Inflated Poisson Regression
I conducted a study on demand of cinema where cinema goers and non-goers both are respondent. and 51% respondents are non-cinema goer. so the frequency of going to cinema hall within last 1 year is more of Zero. 49% respondents went to cinema hall and there responds were like 1,2,3,5 times. this is a cross sectional study. those are count data. so I felt ZIP regression is best because of excess of zero as it has the logit part for excess zero and poisson part for other count data. Now I need appropriate command of stata to conduct the study. I already got some command but I am skiptical. My inflated variables are not found statistically significant. I wonder is it a sign of chosing wrong model?
If I don't have any inflated variable in my mind what to do? because i have few variables in mind as inflated variable. but i am confused. if i take few variables, will it create any problem? like losing degrees of freedom? because I have data of 185 respondents.
I would be grateful if you give me authentic guideline for my study.
