applications in Risk Management, Finance, Economics, Science, and many other areas. This paper develops the theory on both density … . Thereafter, we extend the theory by establishing the density and distribution functions for the quotients Y=X1X2 and Z=X1X1+X2 of … two dependent normal random variables X1 and X2 in the case of Gaussian copulas. We then develop the theory on the median …

. As an application example, cost quantification is then discussed. We also discuss how the mixture model based estimation …
