coef.spmodel {spmodel}

Extract fitted model coefficients

Description

coef extracts fitted model coefficients from fitted model objects. coefficients is an alias for it.

Usage

## S3 method for class 'splm'
coef(object, type = "fixed", ...)

## S3 method for class 'splm'
coefficients(object, type = "fixed", ...)

## S3 method for class 'spautor'
coef(object, type = "fixed", ...)

## S3 method for class 'spautor'
coefficients(object, type = "fixed", ...)

## S3 method for class 'spglm'
coef(object, type = "fixed", ...)

## S3 method for class 'spglm'
coefficients(object, type = "fixed", ...)

## S3 method for class 'spgautor'
coef(object, type = "fixed", ...)

## S3 method for class 'spgautor'
coefficients(object, type = "fixed", ...)

Arguments

object

A fitted model object from splm(), spautor(), spglm(), or spgautor().

type

"fixed" for fixed effect coefficients, "spcov" for spatial covariance parameter coefficients, or "randcov" for random effect variance coefficients. Defaults to "fixed". If type = "spcov", the coefficient vector is an spcov_params() object (which means that has class matching the spatial covariance function used).

...

Other arguments. Not used (needed for generic consistency).

Value

A named vector of coefficients.

Examples

spmod <- splm(z ~ water + tarp,
  data = caribou,
  spcov_type = "exponential", xcoord = x, ycoord = y
)
coef(spmod)
coefficients(spmod)
coef(spmod, type = "spcov")
