Many dataset these days are collected at different locations over space which may generate spatial dependence. Spatial dependence (observation close together are more correlated than those further apart) violate the assumption of independence of the residuals in regression models and require the use of a special class of models to draw valid inference. The first … Continue reading Spatial regression in R part 1: spaMM vs glmmTMB
