I really appreciated this statistics program under GNU General Public License that reproduces the functionality of SPSS. My sincere compliments.
I would suggest to implement in PSPP a complete module of time-series analysis also includes spectral and cross-spectral analysis.
In particular, concerning cross-spectral, the evaluation of the most important parameters such as coherency (with test statistic for non-zero coherency at 80% and 95% level), phase shift and phase shift error (very important).
Best regards.
