Tests for Skewness, Kurtosis, and Normality for Time Series Data We present the sampling distributions for the coefficient of skewness, kurtosis, and a joint test of normality for time series observations. We show that w... Jushan BAI,Serena NG - 《Journal of Business & Economic Statistics》...
The determination of the evolution of the skewness and kurtosis values of the product can be used to establish the normality of the product and how to modelize its distribution. Finally, the Pearson Inequality is proved for the skewness and kurtosis of the product of two normal random variables...

Skewness, Kurtosis, and the Normal Curve偏度,峰度,和正常的曲线.doc,Skewness, Kurtosis, and the Normal Curve( Skewness In everyday language, the terms “skewed” and “askew” are used to refer to something that is out of line or distorted on one side.
One may do an “eyeball test” on measures of skewness and kurtosis when deciding whether or not a sample is “normal enough” to use an inferential procedure that assumes normality of the population(s). If you wish to test the null hypothesis that the sample came from a normal population...
Considering skewness and kurtosis together the results indicated that only 5.5% of distributions were close to expected values under normality. Although extreme contamination does not seem to be very frequent, the findings are consistent with previous research suggesting that normality is not the rule ...
