Economists fit models to data by matching moments or co-moments, but skewness is usually not accounted for. It is so probably because skewness cannot appear in linear (or linearized) models with Gaussian shocks - it requires non-linearities or non-Gaussian shocks. Observed macroeconomic data like...
=SKEW(Data!$B$16:$B$10015)/SQRT($G$5*($G$5-1))*($G$5-2) This is the function I use in the Descriptive Statistics Calculator. The first part – SKEW(Data!$B$16:$B$10015) –is the built-in Excel SKEW function for sample skewness of cells B16 through B10015, and the rest...

We now apply these definition to ...
Gerhard Nahler 56 Accesses AbstractAsymmetry of the distribution of data; a distribution is skewed to the right, when the mean exceeds the median and the right tail is therefore longer than the left (typical for variables with a fixed lower but without upper bound, e.g. number of episodes...
Recent findings suggest that Type I error and power can be adversely affected when data are non-normal. This paper aims to assess the distributional shape of real data by examining the values of the third and fourth central moments as a measurement of skewness and kurtosis in small samples. ...
