Fourier (Spectral) Analysis - Quick Tab
Select the Quick tab of the Fourier (Spectral) Analysis dialog box 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 box. 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 box will be displayed. |
| Dependent variable | Click the Dependent variable button to display a standard variable selection dialog box, in which you specify the dependent variable for the Two series Fourier analysis. |
