1. ### How to make my approach to Monte Carlo simulation and random sample generation more statistically robust?

I´m building a MC simulation models in Excel VBA and R in parallel. Below is my current approach. Please let me know where the weaknesses lie. How could I make my approach more statistically robust without diverging too far from some simplicity? I am particularly concerned with (3) and (5)...

Hi Let's suppose X1 and X2 are two Normally distributed variables. [In general, X1 is from N(m1,s1^2) and X2 from N(m2, s2^2) where m1<m2 and s1^2≠s2^2.] However, let’s say, for the sake of starting the discussion, that both are Normally distributed N(1,2^2) and N(2,3^2). One of X1 or X2 is...
