You are always a valuable, worthwhile human being — not because anybody says so, not because you're successful, not because you make a lot of money — but because you decide to believe it and for no other reason.
We search through historical data looking for anomalous patterns that we would not expect to occur at random. Our scheme is to analyze data and markets to test for statistical significance and consistency over time. Once we find one, we test it for statistical significance and consistency over time. After we determine its validity, weask, ‘Does this correspond to some aspect of behavior that seems reasonable?’
