WebMay 12, 2024 · Chebyshev gives a quantitative answer: in rough terms, it says that an integrable function cannot be too large on large sets, with the power law type decay . (When is too small the inequality becomes rather weak especially in probability theory or when your measure space is otherwise finite so let’s ignore that scenario.) Webgeneral measure theoretic representation and show how the probabilistic statement of Chebyshev’s Inequality is a special case of this. Finally, we prove the Weierstrass Approximation Theorem in Section 4 through a constructive proof using the Bernstein polynomials that were used in Bernstein’s original proof [3] along with Chebyshev’s ...

Chebyshev's inequality states that at most approximately 11.11% of the distribution will lie at least three standard deviations away from the mean. Kabán's version of the inequality for a finite sample states that at most approximately 12.05% of the sample lies outside these limits.
