Introduction

The data are (X₁, Y₁), …, (X_n, Y_n) where X_i is d-dimensional and Y_i is a scalar response variable. We are interested in the conditional expectation function m(x) = E (Y | X = 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).

For an overview of this package, see vignette("prim") for bump hunting and estimating highest density difference regions.
