Structural changes often occur in economics and finance due to changes in preferences, technologies, institutional reforms, policies, crises and other factors. It is important to distinguish whether a structural change is abrupt or evolutionary, because the implications on econometric modelling...

In this paper, we introduce adjusted-range based Kolmogorov-Smirnov (KS) type statisticsto test for structural breaks in the mean of a process and also in a more general setting. We propose a normalization based on the adjusted-range of a partial sum, which is stochastically proportional to the...

We estimate and test for multiple structural breaks in distribution with unknown break dates via a characteristic function approach. By minimizing the sum of squared generalized residuals, we can consistently estimate the break fractions. We propose a sup-F type test for structural breaks in...
