Transformations of Variables - Shift Tab

Select the Shift tab of the Transformations of Variables dialog box to access options that create a variety of transformations that shift the series forward or backward, relative to all other series currently in the active work area.

Element Name Description
OK (Transform selected series) Click the OK (Transform selected series) button to transform the selected variable (series) and display a plot of the analysis. Transformed variables are appended to the active work area. If a transformation produces an invalid value (e.g., square root of a negative value, division by zero, etc.), STATISTICA assigns a missing data value; then, in a second pass, those missing data are replaced according to your selection on the Time Series Analysis Startup Panel - Missing Data tab.
Transformation Use the options in the Transformation group box to select the desired type of transformation.
Shift (lag) series forward If you select the Shift (lag) series forward option button, the series is shifted forward by the number of observations specified in the adjacent Lag= box.
Shift (lag) series back If you select the Shift (lag) series back option button, the series is shifted backward by the number of observations specified in the adjacent Lag= box.
