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 class 'frfast':
summary(object = model, ...)

Arguments

object

a fitted frfast object as produced by frfast().

...

additional arguments affecting the predictions produced.

Value

• summary.frfast computes and returns a list of summary information for a fitted frfast object.
• model
  type of model: nonparametric or allometric.
• 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.

Details

print.frfast tries to be smart about summary.frfast.

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
summary(fit3)
