Abstract
The Average Conditional Exceedance Rate and Peak Over Threshold Markov Chain Monte Carlo are two extreme value statistical methods, compared in this work. They are tested for both extrapolations and prediction intervals. The methods are compared for difference scenarios concluding that the Peak Over Threshold Markov Chain Monte generally prefered better for prediction intervals. It also seems to be preferable for extrapolation of independent and identically distributed data, and data approximately so. There are some indications that the Average Conditional Exceedance Rate method maybe favorable for capturing the data dependencies and extrapolation for correlated observations, but more work is needed for a conclusive result on that aspect.
