• Ridge analysis is a technique useful in connection with the fitting of second-order response surfaces. It enables a path of maximum predicted ŷ values (maximum on a sphere of radius R) to be specified, and followed out from the origin of the experimental region, as R increases. (Alternatively, a minimum ŷ path can be followed out.) This article discusses the addition of a measure of uncertainty to the selected path, thus providing an assessment of the reliability of the ridge analysis as a path progresses. The utility of this method is illustrated by applications to two datasets.
