To some extent, skewness also is indicated by Pearson's first or second measure of skewness. The variance and its square root, the standard deviation or root mean square deviation, are the measures of variability that are used by the statistician....
and this formula is used in finding the center of mass of the points. In statistics, the values are no longer masses, but as we will see, moments in statistics still measure something relative to the center of the values.
of the spectral parameter. as is well-known, in the limit of large sizes of the matrix the logarithm of that modulus is very intimately related to 1 / f noises [ 1 , 2 , 21 , 27 , 28 ]. in that example the interesting quantity is obviously the statistics of the maximum, wi...

It is dynamic as it can measure the extent of higher-order moments connectedness in the time domain. It is directional since it traces the origin of the spillover transmission, thus indicating the contributors to the higher-order moments connectedness using the normalized elements of the ...
Given all moments of the marginals of a measure on Rn, one provides (a) explicit bounds on its support and (b), a numerical scheme to compute the smallest box that contains the support. It consists of solving a hierarchy of generalized eigenvalue problems associated with some Hankel matrices...
Those variables can be used to measure the shape of the dose distribution.Methods:The mean dose, coefficient of variation, skewness, and kurtosis were used to analyze the dose distributions inside PTVs for 24 randomly selected patients. The bin width of the relative dose distribution is 0.1 ...
The compelling reason why a General Autoregressive Conditional Volatility Skewness Kurtosis (GARCHSK) model is employed to construct the marginal distributions of returns is that based on the assumption that skewness and kurtosis are constant, GARCH class methods can only measure conditional variance [20...
Although they suggest that the non-normal distribution may have implications for diversification benefits, they did not pursue the analysis to directly measure this through these higher moments. Even for studies on the US, direct examination of higher moments is usually quite limited, and approaches ...
