Kriging analysis of mean annual precipitation, Powder River Basin, Montana and Wyoming
M.R. Karlinger, James A. Skrivan
1981, Water-Resources Investigations Report 80-50
Kriging is a statistical estimation technique for regionalized variables which exhibit an autocorrelation structure. Such structure can be described by a semi-variogram of the observed data. The kriging estimate at any point is a weighted average of the data, where the weights are determined using the semi-variogram and an assumed...
