. . . . . Statistics, down to Earth

We provide a number of software macros to students in our Applied Environmental Statistics course for computing interesting statistics. Posted here is a SAS macro for computing the squared-ranks test, and an older executable to calculate the Seasonal Kendall and Mann-Kendall tests for trend. A more up-to-date version of the trend software, which includes the Regional Kendall test for trend, is available from the US Geological Survey at
