Abstract
So far we have studied mathematical models of market returns, volatility, interest rates, option prices, and other such financial quantities. These models involve unknown distributions and parameters which need to be calibrated to the prices observed in the market. We would also like to have a measure of reliability of the model and the parameters. Once the models are trained with data, we need to rate their performance. For all these purposes, statistical tools are necessary. We devote the rest of the book to these methods.
