	Statistics of Weather and Climate Extremes
		This web page is intended to serve as a resource for the use of the statistical theory of extreme values in the analysis of weather and climate extremes and their impacts.
		In terms of the tail of a distribution, the corresponding theorem states that the observations exceeding a high threshold, under very general conditions, are approximately distributed as the generalized Pareto distribution [of which the exponential (light tail) and Pareto (heavy tail) are special cases].
		The modern approach to extreme value analysis is based on a point process representation, equivalent to: (i) a Poisson process governing the rate of occurrence of exceedance of a high threshold; and (ii) a generalized Pareto distribution for the excess over the threshold.

	The Extreme Value Approach to VaR - An Introduction, Part 1, by Kevin Dowd
		None of these approaches comes to terms with the basic issue posed by extreme value estimation: that the estimation of low frequency events with limited data is highly problematic, and that these difficulties increase, as these events become rarer.
		The result is extreme value theory-a tailor-made approach to these problems that focuses on the distinctiveness of extreme values.
		The key to this approach is the extreme value theorem, which tells us what the asymptotic distribution of extreme values should look like.

	The First Derivative: Maxima and Minima - HMC Calculus Tutorial
		We cannot find regions on which f is increasing or decreasing, relative maxima or minima, or the absolute maximum or minimum value of f on [-2,3] by inspection.
		According to the Extreme Value Theorem, if a function is continuous on a closed interval, then it achieves both an absolute maximum and an absolute minimum on the interval.
		If f has an extreme value on a closed interval, then the extreme value occurs either at a a critical point or at an endpoint.

	The Extreme Value Theorem
		How the Extreme Value Theorem can fail if the function is not continuous.
		Explanation: The reason that f, which is a continuous function, can get away with not attaining a minimum value is that the interval (0,1] is not closed.
		It follows that h(x) assumes both arbitrarily large and arbitrarily negative values on the interval [-1,1], so it has neither a maximum nor a minumum on this closed interval.

	Properties of Continuous Functions
		Objectives: In this tutorial, we investigate two important properties of functions which are continuous on a closed interval [a, b]: the Intermediate Value Theorem and the Extreme Value Theorem.
		After working through these materials, the student should be able to apply the Intermediate Value Theorem, to determine whether certain functions have roots, and use the bisection method to find roots to any degree of accuracy.
		While the Extreme Value Theorem may seem intuitively obvious, it is a difficult theorem to prove.
