can have difficulty handing shifts that take place during our sample period.
如果在研究的数据中心出现极端事件,会影响很长一段时间。

most(if not all)non-parametric methods are subject(to a greater or lesser extent)to the phenomenon of ghost or shadow effects.
大部分非参数法会受到鬼影效应的影响。
Generally make no allowance for plausible events that might occur,but did not actually occur,in our sample period.
