% The code is explained in the article: Okunev, Pavel, "Fast Computation of
% the Economic Capital, the Value at Risk and the Greeks of a Loan Portfolio
% in the Gaussian Factor Model" (July 1, 2005). http://ssrn.com/abstract=758505
% This implements one factor Gaussian model.
% L = exposures,as fraction of total
% portfolio, taking into account the recovery rate
% Example: loan 1 is 0.01 fraction of the total portfolio, recovery rate is
% 40% then L(1)=0.01*(1-0.4)
% w = loading factors
% p = default probabilities
% LL = loss level expressed as a fraction 99% = 0.99
% N number of names in the portfolio
% pd = probability that portfolio loss will not exceed LL
