Query: Test for parameter change in the presence of outliers: the density power
  divergence based approach   This study considers the problem of testing for a parameter change in the
presence of outliers. For this, we propose a robust test using the objective
function of minimum density power divergence estimator (MDPDE) by Basu et al.
(Biometrika, 1998), and then derive its limiting null distribution. Our test
procedure can be naturally extended to any parametric model to which MDPDE can
be applied. To illustrate this, we apply our test procedure to GARCH models. We
demonstrate the validity and robustness of the proposed test through a
simulation study. In a real data application to the Hang Seng index, our test
locates some change-points that are not detected by the previous tests such as
the score test and the residual-based CUSUM test.
