Skew coefficient

WebbG = coefficient of skew of log values; N, X, and S L are defined as above Skew represents the degree of curvature to the flow-frequency curve as shown in Figure 4-3. In Figure 4-3 the X-axis scale is probability (symmetric at about AEP = 0.5) and the Y-axis scale is base 10 logarithmic flow. WebbFollowing this, Pearson, K. (1894,1895) introduced a coefficient of skewness, known as the \( { \beta_1 } \) coefficient, based on calculations of the centered moments.This coefficient is more difficult to calculate but it is more descriptive and better adapted to large numbers of observations.. Pearson, K. also created the coefficient of kurtosis (\( { …
