I am working on Urban nature access model for population group radii, in the only reference that I have found which included an application for this model, Poisson regression was used as a decay function.
I can not see Poisson in the option list of decay function in the model, I am wondering if it is removed from the model or there is a way that I can get it.
@esoth is correct, the Poisson regression model, while cited in the paper you mention (https://doi.org/10.1016/j.landusepol.2022.106107), was not specified in the model’s design, and so has not yet been implemented. Having said that, we plan to add the Poisson kernel in a future release, in part because it was described, if not formally specified, in this paper. At this time, the only way to include a Poisson kernel would be to modify the source code, or else to wait until we can implement it.
