More on that in a bit…. The coin is a fair coin and thus if we toss the coin many times the expected breakdown between heads and tails will be normally distributed. Tiebreaker has been perpetually tracked since September 2014 with consistent low volatility (6.16 max drawdown) while outperforming its benchmark as measured by Total returns, Sharpe, IR and R-Squared. There is a closely related three aspects, and these aspects affect each other directly. Imagine you run a deep neural network (DNN) experiment to train a stock predictor model and Tensor Board shows a validation precision of 59%. To put it simply, the lower the P-Value the less likely the outcome is due to luck. 14 0 obj The calculations in this material can be very long, involved, repetitive, and use extensive subscript notation; begin by understanding the intent of the calculations and then practice making them.
