Abramson's Adaptive Bandwidths
Description
Computes adaptive smoothing bandwidths according to the inverse-square-root rule of Abramson (1982).
Usage
bw.abram(X, h0, ...)
Arguments
X |
Data to be smoothed. |
h0 |
Global smoothing bandwidth. A numeric value. |
... |
Additional arguments passed to methods. |
Details
This function computes adaptive smoothing bandwidths for a dataset, using the methods of Abramson (1982) and Hall and Marron (1988).
The function bw.abram is generic. There is a method
bw.abram.ppp
for spatial point patterns (objects of class "ppp"),
and possibly other methods.
Value
See the documentation for the particular method.
