Description
            The module is dedicated to finance. There are three main areas that are covered:
(i) risk measure and management, (ii) asset allocation, and (iii) pricing.

For what concerns the risk measure, some functions are dedicated to the
computation of Value at Risk (VaR) and Expected Shortfall (ES). Backtest is also
implemented in order to check the goodness of such risk measures. Both VaR and
ES are also computed in an Extreme Value Theory framework (EVT). Furthermore, it
is possible to estimate the parameters of the EVT density function (through
maximum likelihood). The Mean Excess Function for graphical study of an EVT
distribution is also implemented.
The interest rate risk is faced by functions aimed at computing duration,
convexity, and yield to maturity. Furthermore, Merton, Vasicek and Cox,
Ingersoll and Ross interest rate models are implemented together with the
estimation of their parameters. Parametric interpolation of the interest rate
curve is possible through both Svennson’s and Nelson-Siegel’s models.
Finally, some technical analysis indicators are implemented: Bollinger bands,
moving averages, Hurst index.

The asset allocation problem is faced by two functions which compute: (i) the
optimal portfolio minimizing the variance of its return and (ii) the optimal
portfolio minimizing the expected shortfall of its return. In both cases, the
portfolios with and without a riskless asset and with and without short selling
are computed.

Pricing problem is approached through functions aimed at: (i) computing the
spread on Interest Rate Swaps, (ii) computing the value of options in the Black
and Scholes framework (with Greeks and implied volatility), (iii) simulating
stochastic processes (through Euler discretization).
