Fourier (Spectral) Analysis - Quick Tab

Select the Quick tab of the Fourier (Spectral) Analysis dialog to access the options described here.

Element Name	Description
Single series Fourier analysis	Click the Single series Fourier analysis button to perform a spectrum analysis for the currently highlighted variable (series) and then display the Single Series Fourier (Spectral) Analysis Results dialog. If selected, the transformations specified in the Transformation of input series group box (on the Advanced tab) will be performed prior to the analysis.
Two series Fourier analysis (select dependent var.).	Click the Two series Fourier analysis button to perform a cross-spectrum analysis of the currently highlighted variable (series) and another variable (selected via Dependent variable, see below). The currently highlighted variable will be treated as the independent or x variable in the analyses. Then, the Single Series Fourier (Spectral) Analysis Results dialog will be displayed.
Dependent variable	Click the Dependent variable button to display a standard variable selection dialog, in which you specify the dependent variable for the Two series Fourier analysis.
