Geostatistical techniques analyze and describe the spatial dependence and quantify the scale and intensity of the spatial variation providing the essential spatial information for local estimation. Environmental variables usually show spatial dependence among observations, which is an important drawback to traditional statistical methods. The statistical model proposed is a Gaussian spatial linear mixed model (GSLMM) which introduces in the model various interesting terms un
