SWSTAT

SWSTAT contains a number of options for statistically analyzing time-series data. The time-series data are read from a Watershed Data Management (WDM) file.

The computed statistics and (or) time series can be written back to the WDM file or to a text file.
Uses flow-duration analysis and class intervals to compute absolute error, root mean square error, and bias by class interval for two time series. The standard error of estimate is computed. The flow-durations curves can be plotted. Data may be any time step.
