Asymptotic Behavior of Tail Density for Sum of Correlated Lognormal Variables
We consider the asymptotic behavior of a probability density function for the sum of any two lognormally distributed random variables that are nontrivially correlated. We show that both the left and right tails can be approximated by some simple functions. Furthermore, the same techniques are applie...
