| Research Abstract |
The Lagrange multiplier test is proposed for the null hypothesis that the bivariate time series has the only common stochastic volatility and no idiosyncratic volatility factor. The test statistic is derived by representing the model in the linear state-space form under the assumption that the log of squared measurement error is normally distributed.
