WebJun 24, 2003 · The Gumbel distribution selected arises as the limiting distribution for minima. ... Although the intended basis for its selection was extreme value theory, the mathematical motivation proposed was invalid and consequently no theoretical justification supports this choice. Both models were fitted separately to each of the test data sets, ... WebJan 26, 2016 · One version of the result is: if ϵ i ∼ i i d, Gumbel ( μ, 1), ∀ i, then: E [ max i ( δ i + ϵ i)] = μ + γ + ln ( ∑ i exp { δ i }), where γ ≈ 0.52277 is the Euler-Mascheroni constant. I've checked that this makes sense using R, and it does. The CDF for the Gumbel ( μ, 1) distribution is: G ( ϵ i) = exp ( − exp ( − ( ϵ i − ...
