Serially Correlated Differences in the Paired Comparison of Time Series
时间序列配对比较中的序列相关差值
If observations are taken at the same set of time points on each of two time series whose nonnegative trends are proportional, the F statistic based on the differences of the two series at the time points may be used to test equality of trends against inequality of trends provided the paired differences are independently and identically distributed normal random variables. The present paper investigates the effect on the F test when the paired differences follow a stationary…
