Hello
I want to analyse a dependent variable (donations) as a function of some variables.
The donations data have lots of zeros because most people donate nothing. Other than zeros, donations can range from 1 to a very high number (continuous data).
What would be the best way to model the above? A inverse hyperbolic sine transform? If so, how to interpret the coefficients? Or is there some specific models to deal with zero-inflated data (non-count)?
Thanks,
Umar
