DislikedIn the quant analysis, one of the most important question is how do you avoid data overfitting bias - there are hundreds of articles on this (pretty much every stats discussions leads here) - check the discussion here https://www.reddit.com/r/algotrading/comments/6febbf/dangers_of_backtest_overfitting_marcos_lopez_de/ So my questions is how to you make sure the correlations you are finding are not spurious by chance and have some real predictive power.
