WebThe bound from Chebyshev is only slightly better. With Chernoff, the bound is exponentially small in clnc times the expected value. This is a huge difference. For example, using Chernoff Bounds, Pr(T ≥ 2Ex(T)) ≤ e−38 if Ex(T) = 100. In this case Markov would only give 1/2, and the one-sided extension of Chebyshev would only give 1/(22 +1 ...

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.

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

WebChebyshev's inequality is a "concentration bound". It states that a random variable with finite variance is concentrated around its expectation. The smaller the variance, the stronger the concentration. Both inequalities are used to claim that most of the time, random variables don't get "unexpected" values.

WebOct 11, 2004 · Cherno gives a much stronger bound on the probability of deviation than Chebyshev. This is because Chebyshev only uses pairwise independence between the r.v.s whereas Cherno uses full independence. Full independence can some times imply exponentially better bounds. 9.5.2 Coloring a hypergraph Consider the following problem.

Webtake large values, and will usually give much better bounds than Markov’s inequality. Let’s revisit Example 3 in which we toss a weighted coin with probability of landing heads 20%.
