Dear list, I have two maps of two variables (A and B) obtained by kriging independantly one to the other. I am interested by the map of the C variable which is the multiplication of A*B. I can so obtained the map of C by calculating the product A*B at each node of the grid. How can I obtained the kriging variance map of the C variable? Do you think I can use the definition of the variance(A*B) = E((AB)²)-(E(AB))² by replacing E(AB) by the estimation of AB obtained from the two initials maps for each grid node ? If it isn't true, what solution can I use?
