prim-package | R Documentation |
PRIM for bump-hunting for high-dimensional regression-type data.
The data are (X_1, Y_1), …, (X_n, Y_n) where X_i is d-dimensional and Y_i is a scalar response. We wish to find the modal (and/or anti-modal) regions in the conditional expectation m(x) = E(Y | x).
PRIM is a bump-hunting technique introduced by Friedman & Fisher (1999), taken from data mining. PRIM estimates are a sequence of nested hyper-rectangles (boxes).
