- Ljung-Box test for the cross correlation in mean of multivariate time series with conditional heteroscedasticity tends to suffer from severe size distortions.
- Wild bootstrap-based Ljung-Box test for cross correlations in mean of multivariate time series is proposed.
- According to the simulation study, wild bootstrap-based Ljung-Box test shows no size distortion and comparable powers in the presence of conditional heteroscedasticity.
In the literature, the conventional Ljung-Box test for financial time series with ARCH effect (also known as conditional heteroscedasticity) is well-known to suffer from severe size distortions. The objective of this paper is to develop a wild bootstrap-based Ljung-Box test for cross correlations in mean of multivariate time series. According to our simulation study, the wild bootstrap-based Ljung-Box test succeeds to achieve correct sizes and comparable powers in the presence of ARCH effect.
