Here, I have a time series data of precipitation of two stations of the same place in CSV format. I am trying to find these two stations precipitation trend as well as the magnitude of the trend. For doing that I used Mann-Kendall and Sen's slope. I tried in this particular way, I want to know whether I am doing right or not? In this below code, I calculate trend and magnitude individually but my aim is to calculate trend and magnitude of two stations together. How I can perform the pre-whitening, Mann-Kendall and Sen's slope test for two stations at once as well as their plot?
