WebThe skewness of a price data series is measured in terms of the third moment about the mean of the distribution. If the distribution is symmetric, the skewness is zero. The measure of skewness is given by. The kurtosis describes the extent of the peak of a distribution, that is how peaked it is. WebMar 24, 2024 · Pearson's Skewness Coefficients. Given a statistical distribution with measured mean, statistical median, mode, and standard deviation , Pearson's first skewness coefficient, also known as the Pearson mode skewness, is defined by. which was incorrectly implemented (with a spurious multiplicative factor of 3) in versions of the Wolfram …
