binning {ks} | R Documentation |
Linear binning for 1- to 4-dimensional data.
binning(x, H, h, bgridsize, xmin, xmax, supp=3.7, w, gridtype="linear")
x |
matrix of data values |
H,h |
bandwidth matrix, scalar bandwidth |
xmin,xmax |
vector of minimum/maximum values for grid |
supp |
effective support for standard normal is [-supp,supp] |
bgridsize |
vector of binning grid sizes |
w |
vector of weights. Default is a vector of all ones. |
gridtype |
not yet implemented |
Code is used courtesy of M.P. Wand. Default bgridsize
are
d=1: 401; d=2: rep(151, 2); d=3: rep(31, 3); d=4: rep(21,4).
Returns a list with 2 fields
counts |
linear binning counts |
eval.points |
vector (d=1) or list (d>2) of grid points in each dimension |
