binning: Binning in 1D, 2D or 3D

In aws: Adaptive Weights Smoothing

Binning in 1D, 2D or 3D

Description

The function performs a binning in 1D, 2D or 3D.

Usage

binning(x, y, nbins, xrange = NULL)

Arguments

x	design matrix, dimension n x d, d %in% 1:3.
y	either a response vector of length n or NULL
nbins	vector of length d containing number of bins for each dimension, may be set to NULL
xrange	range for endpoints of bins for each dimension, either matrix of dimension 2 x d or NULL. xrange is increased if the cube defined does not contain all design points.

Value

A list with components

x	matrix of coordinates of non-empty bin centers
x.freq	number of observations in nonempty bins
midpoints.x1	Bin centers in dimension 1
midpoints.x2	if d>1 Bin centers in dimension 2
midpoints.x3	if d>2 Bin centers in dimension 3
breaks.x1	Break points dimension 1
breaks.x2	if d>1 Break points dimension 2
breaks.x3	if d>2 Break points dimension 3
table.freq	number of observations per bin
means	if !is.null(y) mean of y in non-empty bins
devs	if !is.null(y) standard deviations of y in non-empty bins

Note

This function has been adapted from the code of function binning in package sm.
