描述-----Description-----
This function includes two approaches to analyze for trend, the Zhang method and Yue and Pilon method. These differ in their approach to pre-whitening to removing lag-1 autocorrelation. The magnitude of the trend is computed using the Theil-Sen approach (TSA).
此功能包括两种分析趋势的方法:Zhang方法和Yue and Pilon方法。这些不同之处在于其用于预增白以消除lag-1自相关的方法。使用Theil-Sen方法(TSA)计算趋势的大小。
In the Zhang method, trend is removed from the series if it is significant and the autocorrelation is computed. This process is continued until the dfferences in the estimates of the slope and the AR(1) in two consecutive iterations are smaller than 1 percent. The Mann-Kendall test for trend is then run on the resulting time series and TSA is used to compute the slope of the trend.
在Zhang方法中,如果趋势显着,则将其从序列中删除,并计算自相关。继续此过程,直到两次连续迭代中的斜率和
