Calculate Model Observability Matrix

Description

Calculate the singular values of the observability matrix of a model.

Usage

    observability(model)
    ## S3 method for class 'ARMA':
    observability(model)
    ## S3 method for class 'SS':
    observability(model)
    ## S3 method for class 'TSestModel':
    observability(model)

Arguments

model An object containing a TSmodel.

Details

If all singular values are significantly different from zero the model is observable.

Value

The singular values of the observability matrix.
