  2. Extreme value theorem - Wikipedia

    en.wikipedia.org/wiki/Extreme_value_theorem

    The extreme value theorem was originally proven by Bernard Bolzano in the 1830s in a work Function Theory but the work remained unpublished until 1930. Bolzano's proof consisted of showing that a continuous function on a closed interval was bounded, and then showing that the function attained a maximum and a minimum value.

  3. Maximum and minimum - Wikipedia

    en.wikipedia.org/wiki/Maximum_and_minimum

    However, the normalised sinc function (blue) has arg min of {−1.43, 1.43}, approximately, because their global minima occur at x = ±1.43, even though the minimum value is the same. [7] In mathematics, the arguments of the maxima (abbreviated arg max or argmax) and arguments of the minima (abbreviated arg min or argmin) are the input points ...

    The standard Gumbel distribution is the case where = and = with cumulative distribution function = ()and probability density function = (+).In this case the mode is 0, the median is ⁡ (⁡ ()), the mean is (the Euler–Mascheroni constant), and the standard deviation is /

    However, the normalised sinc function (blue) has arg min of {−1.43, 1.43}, approximately, because their global minima occur at x = ±1.43, even though the minimum value is the same.

    The Fisher–Tippett–Gnedenko theorem is a statement about the convergence of the limiting distribution , above. The study of conditions for convergence of to particular cases of the generalized extreme value distribution began with Mises (1936) [3] [5] [4] and was further developed by Gnedenko (1943).

  7. Fréchet distribution - Wikipedia

    en.wikipedia.org/wiki/Fréchet_distribution

    In hydrology, the Fréchet distribution is applied to extreme events such as annually maximum one-day rainfalls and river discharges. [7] The blue picture, made with CumFreq , illustrates an example of fitting the Fréchet distribution to ranked annually maximum one-day rainfalls in Oman showing also the 90% confidence belt based on the ...

  8. Extreme value theory - Wikipedia

    en.wikipedia.org/wiki/Extreme_value_theory

    Extreme value theory or extreme value analysis (EVA) is the study of extremes in statistical distributions. It is widely used in many disciplines, such as structural engineering , finance , economics , earth sciences , traffic prediction, and geological engineering .

  9. Frequency of exceedance - Wikipedia

    en.wikipedia.org/wiki/Frequency_of_exceedance

    Consider a scalar, zero-mean Gaussian process y(t) with variance σ y 2 and power spectral density Φ y (f), where f is a frequency. Over time, this Gaussian process has peaks that exceed some critical value y max > 0. Counting the number of upcrossings of y max, the frequency of exceedance of y max is given by [1] [2]
