"WebMarkov'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)2 with a = ( kσ) 2 : It can also be proved directly using conditional expectation : " - Markov and chebyshev inequality

Web4 jun. 2024 · This inequality was discovered independently by I. Bienaymé (1853) and P.L. Chebyshev (1866). In modern literature this inequality is usually referred to as Chebyshev's inequality, possibly because the name of Chebyshev is associated with an application of it in the proof of the law of large numbers (a theorem of Chebyshev). Web6 apr. 2024 · We present simple randomized and exchangeable improvements of Markov's inequality, as well as Chebyshev's inequality and Chernoff bounds.
