Finding cvar with variance and mean
WebThe variance is the average of the squared deviations from the mean, i.e., var = mean (x), where x = abs (a - a.mean ())**2. The mean is typically calculated as x.sum () / N, where N = len (x) . If, however, ddof is specified, the divisor N - ddof is used instead. 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.
