Projection Pursuit regression (PPR) approximates a regression function f(X ) by a ÿnite sum of ridge functions L l=1 f l ( T l X ). When the explanatory vector X is normally distributed, Johansen and Johnstone (1990) gave an one-term approximation formula to the signiÿcance level of a test of H0: f=
The idea of searching for orthogonal projections, from a multidimensional space into a linear subspace, as an aid to detecting non-linear structure has been named exploratory projection pursuit. Most approaches are tied to the idea of searching for interesting projections. Typically, an interesting
