Abstract
In this paper we propose a new goodnessoffit testing scheme for the marginal distribution of regimeswitching models. We consider models with an observable (like threshold autoregressions), as well as, a latent state process (like Markov regimeswitching). The test is based on the KolmogorovSmirnov supremumdistance statistic and the concept of the weighted empirical distribution function. The motivation for this research comes from a recent stream of literature in energy economics concerning electricity spot price models. While the existence of distinct regimes in such data is generally unquestionable (due to the supply stack structure), the actual goodnessoffit of the models requires statistical validation. We illustrate the proposed scheme by testing whether a commonly used Markov regimeswitching model fits deseasonalized electricity prices from the NEPOOL (U.S.) dayahead market.
