coef.spmodel function

Extract fitted model coefficients

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

## 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).

Returns

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")
