summary.frfast: Summarizing fits of frfast class

Description

Takes a fitted frfast object produced by frfast() and produces various useful summaries from it.

Usage

# S3 method for frfast
summary(object = model, ...)

Value

summary.frfast computes and returns a list of summary information for a fitted frfast object.

model

type of model: nonparametric or allometric.

smooth

type of smoother: kernel or splines.

h

the kernel bandwidth smoothing parameter.

dp

degree of the polynomial.

nboot

number of bootstrap repeats.

kbin

number of binning nodes over which the function is to be estimated.

n

sample size.

fmod

factor's levels.

coef

if model = "allo", coefficients of the model.

Arguments

object

a fitted frfast object as produced by frfast().

...

additional arguments affecting the predictions produced.

Examples

library(npregfast)
data(barnacle)

# Nonparametric regression without interactions
fit <- frfast(DW ~ RC, data = barnacle, nboot = 100) 
fit
summary(fit)

# Nonparametric regression with interactions
fit2 <- frfast(DW ~ RC : F, data = barnacle, nboot = 100)
fit2
summary(fit2)

# Allometric model
fit3 <- frfast(DW ~ RC, data = barnacle, model = "allo", nboot = 100)
fit3
