Abstract:
|
We study the problem of determining if two time series are correlated in the mean and variance processes. Several test statistics, originally designed for determining a connection between two mean processes, are explored and formally introduced for determining a connection in variance. Simulations demonstrate the theoretical asymptotic distribution can be ineffective in finite samples. A parametric bootstrapping method is shown to be an effective tool in such an enterprise. A simulation study demonstrates the efficacy of the bootstrapping method. Lastly, an empirical example explores a connection between the Standard & Poor's 500 index and the Euro/US dollar exchange rate and demonstrates a level of robustness for the proposed method.
