## PortfolioAnalytics Library 

A python library that provides semi-analytical functions useful for testing the accuracy of credit portfolio simulation models

The basic formulas are reasonably simple and well known: They underpin the calculation of RWA (risk weighted assets), and in turn required capital, thus ensuring stability for the entire banking systems worldwide

The library provides support for the Monte Carlo testing framework

Dependencies: scipy, sympy

## Examples

Check the jupyter notebooks

### Current Functions

* vasicek_base

* vasicek_base_el

* vasicek_base_ul

* vasicek_lim

* vasicek_lim_el

* vasicek_lim_ul

* vasicek_lim_q

The Vasicek Base family produces finite pool loss probabilities and measures (EL, UL)

The Vasicek Lim family produces asymptotic pool loss probabilities and measures (EL, UL, Quantile)
