%description
Contains performance analysis metrics of track records including
entropy-based correlation and dynamic beta based on a state/space
algorithm. The normalized sample entropy method has been implemented which
produces accurate entropy estimation even on smaller datasets. On a
separate stream, trades from the five major assets classes and also
functionality to use pricing curves, rating tables, Credit Support Annex
and add-on tables. The implementation follows an object oriented logic
whereby each trade inherits from more abstract classes while also the
curves/tables are objects. Furthermore, odds calculators and P&L
back-testing functionality has been implemented for the most widely used
betting/trading strategies including martingale, 'DAlembert', 'Labouchere'
and Fibonacci. Back testing has also been included for the 'EuroMillions',
the 'EuroJackpot', the UK Lotto, the Set For Life and the UK 'ThunderBall'
lotteries. Furthermore, some basic functionality about climate risk has
been included.
