Statistical modeling of spatial attributes aims to estimate dependence parameters, used to interpolate values at unsampled locations within the study area. Thus, the modeling process is conducted with some statistical criteria that ensure reliable predictions representing the actual local variability. This study evaluates different formulations of the Gaussian geostatistical model to reconstruct the surface of phosphorus over the area from the available measurements on 48 experimental plots located in Xanxerê/SC with emphasis on the methodological framework. Choices of covariates in […]
