Estimation of linear combinations and co-kriging

Utilizing the matrix formulation of co-kriging developed previously by the author, the relationship between direct kriging of linear combinations and linear combinations of co-kriged variables is developed. Conditions for equality of the estimators and the kriging variances are examined. By presenting the problem in the context of Hilbert spaces the general relationship is clarified.
