pomp (version 2.2)

coef: Extract, set, or alter coefficients

Description

Extract, set, or modify the estimated parameters from a fitted model.

Usage

# S4 method for listie
coef(object, ...)
# S4 method for pomp
coef(object, pars, transform = FALSE, ...)
# S4 method for pomp
coef(object, pars, transform = FALSE, ...) <- value
# S4 method for objfun
coef(object, ...)

Arguments

object

an object of class ‘pomp’, or of a class extending ‘pomp’

…

ignored

pars

optional character; names of parameters to be retrieved or set.

transform

logical; perform parameter transformation?

value

numeric vector or list; values to be assigned. If value = NULL, the parameters are unset.

Details

coef allows one to extract the parameters from a fitted model.

coef(object,transform=TRUE) returns the parameters transformed onto the estimation scale.

coef(object) <- value sets or alters the coefficients of a ‘pomp’ object.

coef(object,transform=TRUE) <- value assumes that value is on the estimation scale, and applies the “from estimation scale” parameter transformation from object before altering the coefficients.
