In spatial interpolation, the Inverse-Distance Weight (IDW) and Kriging methods are two of the most widely used deterministic and geostatistical models. In deterministic techniques, interpolation is performed using mathematical functions, whereas geostatistics uses statistical an...
Mineral shortages can be avoided if the mineral industry accurately predicts mineral deposits, which is critical given the importance of minerals in Ghana's economy. The goal of this dissertation was to use the block maxima (BM) approach of Extreme Value Theory (EVT) to accuratel...
