coefficients function

Extract Model Coefficients

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

## 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

Returns

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"))
