Test whether object is a valid SSModel object
Function is.SSModel tests whether the object is a valid SSModel
object.
is.SSModel(object, na.check = FALSE, return.logical = TRUE)
object |
An object to be tested. |
na.check |
Test the system matrices for |
return.logical |

Note that the validity of the values in y and Z are not tested.
These can contain NA values (but not infinite values), with condition that
when Z[i,,t] contains NA value, the corresponding y[t,i] must
also have NA value. In this case Z[i,,t] is not referenced in
filtering and smoothing, and algorithms works properly.
Logical value or nothing, depending on the value of
return.logical.
