Question about the anisotropy factor in the sum metric spatiotemporalcovariance gstat
Dear Sara, the anisotropy in the metric spatio-temporal covariance models describes how spatial distances relate to temporal distance (i.e. to answer the question: At which temporal separation (x hours/days/weeks/...) do have two locations 1 m/km/... apart the same correlation?). Every model that includes the metric model has to have a spatio-temporal anisotropy parameter. For more details, please refer to the vignette of gstat [1].

Dear all. I have a question about the sum metric spatiotemporalcovariance function in gstat. I need to understand the theoretical background and the meaning of the anisotropy (Anis) in it. If anyone can help me in this I will be deeply appreciated Best regards Sara [[alternative HTML version deleted]]
