In statistics and econometrics , a structural break in statistical time series is a situation in which the regression parameters are not constant over the entire time series. This means that either the level parameter or the incline parameter or both parameters change.
can also be converted into a so-called structural break model by introducing a dummy variable . The time series is divided into two phases at the structural break and so each phase has its own parameters.
The Chow test is a way of testing for structural breaks.
