Abstract

Objectives. To develop improved statistical methods for sampling environmental variables and for making spatial predictions from these samples, with particular emphasis on better sampling efficiency, statistical robustness the incorporation of information from different sources ¿ including process models ¿ and a robust expression of the uncertainty of these predictions for subsequent risk analysis. We will develop robust likelihood-based estimators for spatial variance models and robust methods for predicting variables from data that include outliers so that the effect of these is minimized and we can describe the spatial distribution of the outliers so as to estimate the local risk that they occur. We shall develop likelihood methods for robust estimation of co-regionalization models. We shall extend our adaptive methods for spatial sampling to incorporate robustness. We shall develop methods to combine process models with statistical prediction from various data sources of uneven quality. The deliverable for this objective will be a suite of methods, illustrated with agri-environmental case studies, which will have greater flexibility than current classical geostatistical tools.
