I am preparing a project for spatial statistics seminar that examines how to estimate a point pattern intensity as a function of spatial covariates. I have already covered some data set available in R, namely copper and chorley in spatstat.
Next, I would like to give an example from zoology that uses two continuous numerical covariates. Hence, I am looking for a suitable data set available online. I have considered gorillas data set in spatstat. However, the relationship isn't that demonstrative. I would appreciate some hints.
