Fisher's skew
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. WebReturn the Gaussian expanded pdf function given the list of 1st, 2nd moment and skew and Fisher (excess) kurtosis. pdf_moments (cnt) Return the Gaussian expanded pdf function given the list of central moments (first one is mean).
