Hi,
I work on a zero-inflated count model (zero-inflated Poisson and
zero-inflated negative binomial) to describe the number of detected H5N1
outbreaks in the subdistricts of Thailand.
I would like to test the residuals of my model for spatial
autocorrelation. But I don't really know how to test it as my model is
not a conventional linear model nor a glm (rather a hierarchical model).
Does a function (such as moran.test() or lm.morantest()) exist for
residuals of hierarchical models (zero-inflated models) ? I cannot find
any clue in the litterature... Would you mind to light me ?
If nothing exists yet, what do you advise me to do ?
Thank you very much for you answer.
Best regards,
Timothée
