The variance ratio test is a statistical method used to assess the presence of a unit root in a time series, which indicates whether the series is non-stationary. Developed by Lo and MacKinlay, it compares the variances of different time intervals of the series to determine if the observed variance is consistent with a random walk model. A significant difference in variances suggests that the series may not be stationary, implying that past values have a persistent effect on future values. This test is commonly used in finance and econometrics to analyze asset prices and economic indicators.

Therefore if on company fails, the probability of others failing increases.
