Summarizing local polynomial fits

Description

summary method for class “npregress”.

Usage

## S3 method for class 'npregress'
summary(object,  criteria="call", ...)

Arguments

object

Object of class npregress.

criteria

Character string which gives the criteria evaluated for the model. The criteria available are GCV (default, "gcv"), AIC ("aic"), corrected AIC ("aicc"), BIC ("bic") or gMDL ("gmdl"). The string "call" return the criterion used in the call of npregress.
