reachability: Calculate Model Reachability Matrix

Description

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

Usage

reachability(model)
    # S3 method for ARMA
reachability(model)
    # S3 method for SS
reachability(model)
    # S3 method for TSestModel
reachability(model)

Arguments

model

An object containing TSmodel.

Value

The singular values of the reachability matrix.

Details

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