Definitions
Best predictor : Predictor having the smallest mean square prediction error (best) of all predictors within a certain class.
Mixed integer model : Model of observation equations having both real-valued and integer-valued unknown parameters.
Introduction
The prediction of spatially and/or temporally varying variates finds its application in various spatial and Earth science disciplines. In physical geodesy, where it is used with a trend-signal-noise model to predict functionals of the gravity field, it is known as least-squares collocation (Krarup, 1969; Moritz, 1978; Sanso and Tscherning, 2003). The trend-signal-noise model also forms the basis of prediction in geostatistics, where optimal linear prediction is called Kriging, named after Krige (1951) and further developed by Matheron (1970). When the trend is unknown, it is referred to as universal Kriging, and when the trend is absent or set to zero, it is called simple Kriging (Herzfeld, 1992; Wackernagel, 1995; Olea, 1999...
