WebSep 1, 2014 · It is basically a variation of the proof for Markov's or Chebychev's inequality. I did it out as follows: V ( X) = ∫ − ∞ ∞ ( x − E ( X)) 2 f ( x) d x. (I know that, properly … Chebyshev's inequality is important because of its applicability to any distribution. As a result of its generality it may not (and usually does not) provide as sharp a bound as alternative methods that can be used if the distribution of the random variable is known. To improve the sharpness of the bounds provided by Chebyshev's inequality a number of methods have been developed; for a review see eg.

The … WebMar 24, 2024 · After discussing upper and lower Markov's inequalities, Cantelli-like inequalities are proven with different degrees of consistency for the related lower/upper previsions. In the case of coherent imprecise previsions, the corresponding Cantelli's inequalities make use of Walley's lower and upper variances, generally ensuring better …

While the inequality is often attributed to Francesco Paolo Cantelli who published it in 1928, it originates in Chebyshev's work of 1874. When bounding the event random variable deviates from its mean in only one direction (positive or negative), Cantelli's inequality gives an improvement over Chebyshev's inequality. See more In probability theory, Cantelli's inequality (also called the Chebyshev-Cantelli inequality and the one-sided Chebyshev inequality) is an improved version of Chebyshev's inequality for one-sided tail bounds. The … See more Various stronger inequalities can be shown. He, Zhang, and Zhang showed (Corollary 2.3) when $${\displaystyle \mathbb {E} [X]=0,\,\mathbb {E} [X^{2}]=1}$$ and $${\displaystyle \lambda \geq 0}$$: See more For one-sided tail bounds, Cantelli's inequality is better, since Chebyshev's inequality can only get $${\displaystyle \Pr(X-\mathbb {E} [X]\geq \lambda )\leq \Pr( X-\mathbb {E} [X] \geq \lambda )\leq {\frac {\sigma ^{2}}{\lambda ^{2}}}.}$$ See more • Chebyshev's inequality • Paley–Zygmund inequality See more
