Zia, I'm not an expert on Kriging, or on the particular package. It sounds like you just want to know how to anti-log the predictions,. which shouldn't be hard. However, depending on what you actually need to predict, it seems your predictions might be biased, right? regards, Farrar Zia Uddin Ahmed <zua3@cornell.edu> wrote: I have a question to everybody.
