Tschebyscheff theorem
In probability theory, Chebyshev's inequality (also called the Bienaymé–Chebyshev inequality) guarantees that, for a wide class of probability distributions, no more than a certain fraction of values can be more than a certain distance from the mean. Specifically, no more than 1/k of the distribution's values can be k … See more The theorem is named after Russian mathematician Pafnuty Chebyshev, although it was first formulated by his friend and colleague Irénée-Jules Bienaymé. The theorem was first stated without proof by … See more As shown in the example above, the theorem typically provides rather loose bounds. However, these bounds cannot in general (remaining true for arbitrary distributions) be improved upon. The bounds are sharp for the following example: for any k ≥ 1, See more Several extensions of Chebyshev's inequality have been developed. Selberg's inequality Selberg derived a … See more Chebyshev's inequality is usually stated for random variables, but can be generalized to a statement about measure spaces. Probabilistic … See more Suppose we randomly select a journal article from a source with an average of 1000 words per article, with a standard deviation of 200 words. We can then infer that the probability … See more Markov's inequality states that for any real-valued random variable Y and any positive number a, we have Pr( Y ≥a) ≤ E( Y )/a. One way to prove Chebyshev's inequality is to apply Markov's inequality to the random variable Y = (X − μ) with a = (kσ) : See more Univariate case Saw et al extended Chebyshev's inequality to cases where the population mean and variance are not known and may not exist, but the sample mean and sample standard deviation from N samples are to be employed to bound … See more WebJul 19, 2013 · The justification for these two false theorems is as follows. Suppose that the Gegenbauer polynomials are normalized so that \(\hat{C}_{n}^{m}(1)=1\), which is also the maximum value of the polynomial on \(x \in [-1, 1]\). (This is not the standard normalization, but has been employed by most authors who have tried to compare rates of convergence …

WebJun 27, 2014 · One drawback of the Tschebyscheff scalarization method is the possibility of obtaining upper set less weakly efficient solutions. In order to avoid this, we will apply the augmented weighted Tschebyscheff scalarization (see, e.g., Steuer and Choo 1983) below. Again, the proof can be found in the appendix. Theorem 13
