TSTooI Documentation <br />Commands <br />TSTooI Fill Techniques and Associated Commands (continued) <br />Techni ue Command T ical Use <br />Historic fillHistMonthAverage () Use with monthly time series to estimate <br />Monthly missing monthly values as the average of <br />Average historic monthly values. For example, if <br /> applied to monthly precipitation data, a <br /> missing July value would be set to the <br /> average of observed July precipitation values <br /> (zero is an observation). <br />Historic Year fillHistYearAverage () Use with yearly time series to estimate <br />Avera e missin data as the avera e of annual values. <br />Interpolation fill Interpolate O Use to estimate missing data by interpolating <br /> between non-missing values. For example, <br /> use to estimate reservoir level chan es. <br />Maintenance f i 11MOVE1 () Use to estimate missing data using the <br />of Variance Maintenance of Variance Extension <br /> (MOVE.1). For example, use to estimate <br /> unregulated streamflow from a related gage. <br /> This command is currentl not enabled. <br />Maintenance f i l1MOVE2 () Use to estimate missing data using the <br />of Variance Maintenance of Variance Extension <br /> (MOVE2). For example, use to estimate <br /> unregulated streamflow from a related gage. <br /> This approach has been shown to be slightly <br /> better than the MOVE.1 a roach. <br />Historic fillPattern O Similar to filling with historic averages with <br />Pattern additional complexity of classifying historic <br />Averages months into categories. For example, <br /> historic averages for wet, dry, and average <br /> periods are computed and used as the <br /> historic averages. This command requires <br /> that the setPatternFile O control <br /> command also be used. <br />Prorate f i1lProrate () Fill a time series by prorating known values <br /> with another time series. <br />Regression fillRegression () Use to estimate missing data by using <br /> ordinary least squares regression. For <br /> example, use to estimate streamflow from a <br /> related a e. <br />Repeat f i 11Repeat () Use when it can be assumed that the last <br /> observed value before a missing period is a <br />good estimate for missing data. For <br /> example, use with "forecasted" data where <br /> no future value is available for inte olation. <br />Using fillUsingDiversionComments () This command is only available with the <br />diversion HydroBase input type and uses diversion <br />comments comments to set additional diversion <br /> amounts to zero. <br />Commands - 7 <br />
