bw.abram | R Documentation |
Computes adaptive smoothing bandwidths according to the inverse-square-root rule of Abramson (1982).
bw.abram(X, h0, ...)
X |
Data to be smoothed. |
h0 |
Global smoothing bandwidth. A numeric value. |
... |
Additional arguments passed to methods. |
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.
See the documentation for the particular method.
