Convert Model Objects between Forms
as_marssMODEL.Rd
These are utility functions for model objects in the package MARSS-package
.
Users would not normally work directly with these functions.
Arguments
- x
An object of class
marssMLE
.- C.and.D.are.zero
If the C and D matrices are all 0, then a marss model can be converted to marxss without further information besides the marss model.
- only.par
If only.par=TRUE then only the par element is changed and marss is used for the marss object.
Details
As the name of the functions imply, these convert marssMODEL
objects of different forms into other forms. form=marss is the base form needed for the internal algorithms, thus other (more user friendly forms) must have a form_to_marss
function to convert to the base form. The printing functions are customized to show output in the user-friendly form, thus a marss_to_form
function is needed for print
and coef
methods for marssMLE
objects.
Value
A marssMODEL
object of the appropriate form.
