Bayesiansk kriging (modelbaseret geostatistik)

Bayesiansk kriging indlejrer klassisk geostatistisk interpolation i en fuld probabilistisk ramme. I stedet for at behandle variogramparametre som faste punktestimater, placeres der priorifordelinger på dem, og disse priorier opdateres med observerede spatiale data for at opnå en posteriorifordeling. Forudsigelser på ikke-samplede lokationer marginaliseres derefter over denne usikkerhed, hvilket giver ærlige prædiktive intervaller, der tager højde for både spatial afhængighed og parameterusikkerhed.
