regband Bandwidth selectors for local regression. regband

Usage:


regband(formula, what = c("CP", "GCV", "GKK", "RSW"), deg=1, ...)

Description:

Function to compute local regression bandwidths for local linear regression, implemented as a front end to locfit().

This function is included for comparative purposes only. Plug-in selectors are based on flawed logic, make unreasonable and restrictive assumptions and do not use the full power of the estimates available in Locfit. Any relation between the results produced by this function and desirable estimates are entirely coincidental.

Arguments:

formula
Model Formula (one predictor).
what
Methods to use.
deg
Degree of fit.
...
Other Locfit options.

Value:

Vector of selected bandwidths.
