coefficients {bayesGAM}

Extract Model Coefficients

Description

Method for bayesGAMfit objects. Extracts the specified quantile of the posterior. The user may specify all or some of the parameters \beta, \epsilon, \lambda, u, sigma, a.

Usage

## S4 method for signature 'bayesGAMfit'
coefficients(
  object,
  params = c("beta", "eps", "lambda", "u", "sigma", "a"),
  FUN = median
)

## S4 method for signature 'bayesGAMfit'
coef(
  object,
  params = c("beta", "eps", "lambda", "u", "sigma", "a"),
  FUN = median
)

Arguments

object

an object of class bayesGAMfit, usually a result of a call to bayesGAM.

params

character vector of the names of parameters to return

• \beta beta

• \epsilon eps

• \lambda lambda

• a] a

FUN

function from which to estimate coefficients. Default is median

Value

Numeric vector of parameter point estimates based on the given prob, with a default of the median estimate.

Examples

require(stats); require(graphics)
f <- bayesGAM(weight ~ np(height), data = women, family = gaussian, 
              iter = 500, chains = 1)
coef(f, params=c("beta", "eps"))
