sponge.grid

This dataset contains 95530 rows of 7 predictive variables including longitude (easting), latitude (northing), topographic position index (tpi3), variance of backscatter (var7), entropy (entro7), backscatter at incidence angle 11 degree (bs11), and backscatter at incidence angle 34 degree (bs34).

Introduction to some novel accurate hybrid methods of geostatistical and machine learning methods for spatial predictive modelling. It contains two commonly used geostatistical methods, two machine learning methods, four hybrid methods and two averaging methods. For each method, two functions are provided. One function is for assessing the predictive errors and accuracy of the method based on cross-validation. The other one is for generating spatial predictions using the method.
