Asynchronicity can be a significant problem for daily or weekly data,as it distorts measured correlations and induces relationships that might not exist if the data were measured synchronously.
对于每日或每周数据来说,异步性可能是一个重大问题,因为它会扭曲测量的相关性,并引发同步测量数据时可能不存在的关系。
老师说异步性会导致correlation被低估。但是根据PPT的文字,异步性会引发不存在的关系。
不是很理解,求解答。
