The basic assumptions of spatial estimation methods; Inverse Distance interpolation methods; Classical statistics: the Normal distribution.
Statistical methods: the lognormal distribution; confidence levels; standard errors; grade/tonnage curves.
Geostatistical methods: the experimental semi-variogram; modelling semi-variograms; trends; anisotropy; geological features
Variations on kriging; lognormal methods; indicator methods; non-linear geostatistics; regression problems (conditional bias); simulation.
