WebThe presence of outliers amongst the variables will generate a large and possibly misleading measure of skewness (Helsel and Hirsch, 1992). Instead, the resistant skewness is a more robust measure for capturing the asymmetrical or symmetrical properties in the data. It is estimated using the following equation: Web6 dec. 2024 · Skewness has been used to represent the symmetry in the data distribution (Helsel and Hirsch, 2002) and kurtosis has been used to represent the tail length of data distribution. Skewness and kurtosis have been used here in order to compare the GWSA estimates from the two satellite-based estimates with the in situ estimate.
