Hello everybody,

I am doing some statistical comparison between wind hourly data
and some explanatory variables. For some days
the target variable seems to be  zero-inflated (many values of zero).
Is there a general rule-of-thumb in deciding when to use pscl-zeroinflated
regression model?


Thank you,
