The tool supports interface of Foresight Analytics Platform 9 or earlier.
To select a missing data treatment method that is used to calculate missing values in variables, use the Missing Data Treatment side panel tab.
If missing data treatment is required, select the Apply checkbox and select one of the methods:
Casewise. Default. Empty values are excluded from the series. Calculations are executed without considering them.
Geometric Interpolation. Empty values of series are calculated using geometric interpolation.
Overlay. Empty values of the output series are replaced with values of the series specified in the Series with Values parameter.
Cubic Spline Interpolation. Empty values of series are calculated using cubic spline interpolation.
Linear Interpolation. Empty values of series are calculated using linear interpolation by two neighbor points.
Linear Trend. Empty values of series are calculated using linear trend.
Pattern. Empty values of series are calculated using pattern interpolation. Select the variable representing the template data series in the Pattern Series parameter.
Previous Value. Empty values of series are replaced with the previous non-empty value.
Random Value. Empty values of series are replaced with a random number that belongs to the interval [minimum series value; maximum series value].
Succeeding Value. Empty values of series are replaced with the succeeding non-empty value.
Average. Empty values of series are calculated as average.
N-Point Average. Empty values of series are calculated as N-point average. Select the number of neighbor points (N) in the Parameter box.
Previous Growth Rate. Empty values of series are calculated based on growth rate of existing values in comparison with the previous period. Select the number of periods in the Parameter box.
Succeeding Growth Rate. Empty values of series are calculated based on growth rate of the existing values for the succeeding period. Select the number of periods in the Parameter box.
Value. Empty values of series are replaced with the value selected in the Parameter box.
