binning {aws} | R Documentation |
The function performs a binning in 1D, 2D or 3D.
binning(x, y, nbins, xrange = NULL)
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. |
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 |
This function has been adapted from the code of function binning in package sm.
