Chebyshev’s inequality是什么
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.

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.)
