The skewness of the normal distribution (or any perfectly symmetric distribution) is zero. The skewness of a distribution is defined as s=E(x−μ)3σ3, where µ is the mean of x, σ is the standard deviation of x, and E(t) represents the expected value of the quantity t. The...
Symmetry of the underlying probability density plays an important role in statistical inference, since the sampling distribution of the sample mean for a given sample size is more likely to be approximately normal for a symmetric distribution than for an asymmetric one. In this article, two new ...

The conditional distribution of asset returns is important for a number of applications in finance, including financial risk management, asset pricing and option valuation. In the GARCH framework, it is typically assumed that returns are drawn from a symmetric conditional distribution such as the norma...
Some distributions of data, such as thebell curveornormal distribution, are symmetric. This means that the right and the left of the distribution are perfect mirror images of one another. Not every distribution of data is symmetric. Sets of data that are not symmetric are said to be asymmetri...
Higher moments of the normal distribution The skewness of a price data series is measured in terms of the third moment about the mean of the distribution. If the distribution is symmetric, the skewness is zero. The measure of skewness is given by (37.14)Skewness = 1nΣi=1n(xi−x¯)...
