查询词典 lag correlation coefficient

In the empirical study, we find that conventional tests over reject the null when the event forecasts and event realization of all countries have high serial correlation, which means the event forecasts have the timing ability. According to the evidence of sample correlation coefficient, however, it seems that the event forecasts have no timing ability by using these the HAC robust tests.

尔后，利用实际的资料，考虑六个国家股票市场每月之报酬率发现，所有国家在事件预测值与事件实现值存在高度的序列相关下，传统检定方法出现了过度拒绝虚无假设的结果，认为事件预测值具有预测能力；而考虑序列相关问题的检定方法则认为事件预测值不具有预测能力。
