WebThis Excel spreadsheet implements a Modified Value at Risk (or MVaR) calculation, which adjusts the standard deviation to account for skew and kurtosis in the returns distribution (greater negative skew and kurtosis act to increase VaR). Value at Risk (VaR) is widely used in the risk management industry to quantify the risk of an investment. WebDec 14, 2014 · Skewness measures the lack of symmetry in a variable. The formula for the Fisher-Pearson skewness coefficient is: where , s, and n are the sample mean, the sample standard deviation, and the sample size, respectively. Note that in computing the skewness, the standard deviation is computed using n in the denominator rather than n - 1.
