Data Processing

Market data is temporal in nature → a series of trading events that will happen in a moment of time.
• t-Statistic
Way of testing probability getting as large of mean with correct assumptions made to build our model of strategy returns
• Probability Density Function (PDF)
An equation that defines a probability distribution; for every number from negative infinity to positive infinity, the PDF gives a probability that this number will be generated
• Box-Cox Transformation
Way to make our data normally distributed & homoscedastic (same over time); a monotonic transformation that changes the value of the dataset, but preserves their relative order
