Seasonal Kendall Test for Trend
       US Geological Survey, 2005

 Data set:  Example SK2c - Seasonal Kendall test, input type 2          

 The record is 50 complete water years with   6 seasons per year
    beginning in water year    2.

 The tau correlation coefficient is  0.028
     S =    206.
     z =   0.763
     p =  0.4457
     p =  0.5824 adjusted for correlation among seasons
                 (such as serial dependence)
 The adjusted p-value should be used only for data with
    more than 10 annual values per season.

 The estimated trend may be described by the equation:

    Y =   0.000     +    0.000     * Time

    where Time = Year (as a decimal) -    1.75 (beginning of first water year)
