I have a dataset which seems to have alota lot of zeroes. I have already fittedfit a poisson regression model as well as a negative binomial model. I would like to fit zero-inflated and hurdle models as well.

Before I do I would like to run a test to investigate whether my data really is zero inflated. IsWhat test(s) is/are there any function to do this in Rdetermine whether my data are zero-inflated?
