## 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.
