Jointly testing linearity and nonstationarity within threshold autoregressions

Author

  • Pitarakis, Jean-Yves

Abstract

A Wald type test of the joint null hypothesis of linearity and nonstationarity within a threshold autoregressive process of order one with deterministic components is developed. Its limiting distribution is derived and its local power and finite sample properties investigated.
