SpletThe expectation of the absolute value of the standard normal is an easily computed constant. So the bound we get from applying the Markov Inequality directly to X is of the form K t. For large t, this is enormously larger than the truth, since it entirely misses the rapidly decaying e − t 2 / 2 term. Share Cite Follow edited Oct 22, 2011 at 15:05 Splet01. jan. 2009 · Abstract.
