Webb28 apr. 2024 · Skewness measures the degree of asymmetry. But when the distribution is symmetric the skewness is 0 (for this example). I don't know how this would come up when dealing with GARCH models. @MichaelChernick, in GARCH models the distribution would be centered at zero but potentially skewed. Webb3.4 Skewed Distributions and Data Transformation. A skewed distribution is neither symmetric nor normal because the data values trail off more sharply on one side than on the other. In business, you often find skewness in data sets that represent sizes using positive numbers (eg, sales or assets). The reason is that data values cannot be less ... rachel davies actress wikipedia
