Obviously there are some real patterns there, but when interpreting low-resolution plots visually, be careful of Moire effects: view the following image at multiple zoom levels as an example. http://upload.wikimedia.org/wikipedia/commons/4/42/Divers_-_Illustrated_London_News_Feb_6_1873-2.PNG My ow

OK, thanks guys for your suggestions, which I'll try tomorrow I did correlation first, but no significant values Then I did linear regression, one sample to rest and while there I spotted this grid pattern I was using pandas lag_plot, but it's same plot when I do MPL scatter one sample on others _

Thanks for your reply I suppose, variable length signals are split on equal parts and dominant harmonic is extracted. Then scatter plot shows this pattern, which has some low correlation, but I can't abstract what could be concluded from grid pattern, as I lack statistical knowledge. Maybe it's sa
