TSTool Documentation Commands <br /> Commands - 7 <br />Technique Command Typical Use <br />parameters with time series at different locations, to <br />use the best combination. <br />Maintenance <br />of Variance <br />FillMOVE1() Us e to estimate missing data using the Maintenance <br />of Variance Extension (MOVE.1). For example, use <br />to estimate unregulated streamflow from a related <br />gage. This command is currently not enabled. <br />Maintenance <br />of Variance <br />FillMOVE2() Use to estimate missing data using the Maintenance <br />of Variance Extension (MOVE.2). For example, use <br />to estimate unregulated streamflow from a related <br />gage. This approach has been shown to be slightly <br />better than the MOVE.1 approach. <br />Historical <br />Pattern <br />Averages <br />FillPattern() Si milar to filling with historic averages with <br />additional complexity of classifying historic months <br />into categories. For example, historic averages for <br />wet, dry, and average periods are computed and used <br />as the historic averages. This command requires that <br />the SetPatternFile() control command also <br />be used. <br />Prorate FillProrate() Fill a time series by prorating known values with <br />another time series. <br />Regression FillRegression() Use to estimate missing data by using ordinary least <br />squares regression. For exa mple, use to estimate <br />streamflow from a related gage. <br />Repeat FillRepeat() Use when it can be assumed that the last observed <br />value before a missing period is a good estimate for <br />missing data. For example, use with "forecasted" <br />data where no future value i s available for <br />interpolation. <br />Using <br />diversion <br />comments <br />FillUsing <br />DiversionComments() This command is only available with the HydroBase <br />input type and uses diversion comments and the “not <br />in use” flag to set additional diversion amounts to <br />zero. <br /> <br />Fill c ommands can be layered (e.g., use F illRegression(), then F illInterpolate(), then <br />F illConstant()). However, the analysis that occurs for each command may be impacted by earlier <br />fill commands. If necessary, use the S etFromTS() command to piece together the results of <br />independent fill commands into a final time series. The Results...Graph – XY -Scatter output provides <br />options for selecting different fill techniques and viewing analysis details. <br /> <br />61
