There is no need for a special function for that, since it is so easy (this is Python 3 code): def Chebyshev_inequality (num_std_deviations): return 1 - 1 / num_std_deviations**2. You can change that to handle the case where k <= 1 but the idea is obvious. In your particular …
The chebyshev inequality
Did you know?
網頁2024年5月16日 · Chebyshev is probably best known for developing an inequality of probability theory which was named Chebyshev’s inequality. It guarantees that, for a wide class of probability distributions, “nearly all” values are close to the mean. More exactly, no more than 1/k2 of the distribution’s values can be more than k standard deviations away ... 網頁Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world.

網頁2024年2月10日 · Markov’s inequality says that for a positive random variable X and any positive real number a, the probability that X is greater than or equal to a is less than or equal to the expected value of X divided by a . The above description can be stated more succinctly using mathematical notation.
