C&ENVENG 7053 - Non-Linear Geostatistics

North Terrace Campus - Semester 2 - 2014

Reasons for using non-linear methods of estimation - outliers, skewed distributions, "best" estimates. Simple ways of dealing with non-linearity: proportional effects, lognormality. Estimation by direct transformation to a Gaussian (normal) distribution - lognormal kriging; multigaussian kriging. Indirect methods - illustrated by heuristic methods in case studies. Hermite polynomial transforms. Disjunctive kriging. Non-parametric estimation - indicator kriging, multiple indicator co-kriging.
