Hi All. I am applying both a log10 transformation as well as arcsine(sqrt) to my data to make the data more consistent with normality. I believe these are both members of the box-cox family. I would like to make countour maps of both kriging predictions and kriging prediction errors on the original scale. How do I back transform to get values on the original scale to make the maps? If there an R function that does the back transforming for me all the better. Thanks, Kerry
