coef function

Extract, set, or alter coefficients

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

## S4 method for signature 'listie'
coef(object, ...)

## S4 method for signature 'pomp'
coef(object, pars, transform = FALSE, ...)

## S4 replacement method for signature 'pomp'
coef(object, pars, transform = FALSE, ...) <- value

## S4 method for signature 'objfun'
coef(object, ...)

## S4 replacement method for signature 'objfun'
coef(object, pars, transform = FALSE, ...) <- value

Arguments

• object: an object of class pomp , or of a class extending pomp
• ...: ignored or passed to the more primitive function
• 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.
