Jan 15, 2017  · Value-at-Risk (Extreme-Value Theory) using Monte Carlo Simulation in R. In short, I’m trying to run the value-at-risk function (first function) within the monte carlo function (second function) and trying to put the average simulated values into a data tables. I know the first function works, but it’s the second function that’s driving me crazy. There are the errors I’m getting:
