It's really hard to tell, especially outside the field, whether someone's computation has found signal and not noise in their data series, or even whether that data series has any significance for different times and different places ...
(You can "Monte Carlo" the past as much as you want, it won't become the future.)
Edit: I probably should have just referenced Sliver's Signal and Noise and left it at that.
