This calculator computes the skewness and kurtosis of a distribution or data set. Skewness is a measure of the symmetry, or lack thereof, of a distribution. Kurtosis measures the tail-heaviness of the distribution. A number of different formulas are used to calculate skewness and kurtosis. This ...
Co‐Kurtosis and Capital Asset Pricing This paper examines the impact of co-kurtosis on asset pricing using a four-moment capital asset pricing model. It is shown that, in the presence of skewness and kurtosis in asset return distribution, the expected excess rate of return i... H Fang,Tso...
The histogram can give you a general idea of the shape, but two numerical measures of shape give a more precise evaluation: skewness tells you the amount and direction of skew (departure from horizontal symmetry), and kurtosis tells you how tall and sharp the central peak is, relative to a...
kyrtos or kurtos, meaning bulging) is any measure of the "peakedness" of the probability distribution of a real-valued random variable.[1] In a similar way to the concept of skewness, kurtosis is a descriptor of the shape of a probability distribution and, just as for skewness, there are...
Population excess kurtosis can be calculated by adjusting the result of KURT (see details how to do it here). You can easily calculate kurtosis, skewness, standard deviation and other measures using the Descriptive Statistics Excel Calculator....
Note that for largesample sizen, the quantity under the radical is near 1, and the standard error of the kurtosis is approximately twice the size of the standard error of the skewness. Anabsolute valueof the ratio that is larger than 1.96 would indicate a shape of a distribution statisticall...
