WebFeb 22, 2024 · CVaR builds on the figures established by VaR, to put potential losses in real terms beyond the specified threshold (breakpoint). For instance, a fund manager might measure VaR at 2% with a 95% confidence level, which means that there’s a 5% chance to lose 2% on any day in the given period. Web15.5 Mean and Variance of the Binomial. Many of the well-known probability distributions, including the binomial distributions, have what I like to call ‘short-cut’ formulas for finding the expected value and variance that is easier than the formulas seen previously for ‘generic’ discrete probability distributions.
