Title: | Geostatistical analysis using K-splines in the geoadditive model | Authors: | VANDENDIJCK, Yannick FAES, Christel HENS, Niel |
Issue Date: | 2015 | Source: | Proceedings of the 30th International Workshop on Statistical Modelling, Volume 2, p. 283-286 | Abstract: | In geostatistics, both kriging and smoothing splines are commonly used to predict a quantity of interest. The geoadditive model proposed by Kammann and Wand (2003) represents a fusion of kriging and penalized spline additive models. The fact that the underlying spatial covariance structure is poorly estimated using geoadditive models is a drawback. We describe K-splines, an extension of geoadditive models such that estimation of the underlying spatial process parameters and predictions of the spatial map are performed with the same accuracy and precision as in kriging. | Notes: | E-mail for correspondence: yannick.vandendijck@uhasselt.be | Keywords: | covariogram; kriging; mixed model; penalized spline | Document URI: | http://hdl.handle.net/1942/19171 | Rights: | The copyright remains with the author(s). | Category: | C2 | Type: | Proceedings Paper |
