Kurtosis and spread Kevin P. BalandaHelen MacGillivray Canadian journal of statistics Mar 1990 An increase in kurtosis is achieved through the location- and scale-free movement of probability mass from the “shoulders” of a distribution into its centre and tails. We introduce a coherent structure...
When we talk about kurtosis in statistics, we’re focusing on two main aspects of a data distribution: tailedness and peakedness. Tailedness in kurtosis refers to the frequency and extremity of outliers in a dataset. Outliers are those unusual values that fall far from the majority of the dat...
Kurtosis In statistics, we use the kurtosis measure to describe the “tailedness” of the distribution as it describes the shape of it. It is also a measure of the “peakedness” of the distribution. A high kurtosis distribution has a sharper peak and longer fatter tails, while a low kurto...
and sharp the central peak is, relative to a standard bell curve. Why do we care? One application is testing for normality: many statistics inferences require that a distribution be normal or nearly normal. A normal distribution has skewness and excess kurtosis of 0, so if your distribution ...
(ix) Statistics weighted by the inverse-squared uncertainties are called ‘error-weighted’ for brevity and interpolation-based weights computed in phase (Rimoldini, 2013a) are named ‘phase weights’. Skewness and kurtosis unbiased by Gaussian uncertainties page 2 of 36 3 Method The goal is to...

Kurtosis was the same for each couple of distributions with the same absolute level of skewness. We can test for skewness-seeking behavior only in the positive–negative treatment because, in the other two treatments, the two distributions did not have the same kurtosis. An individual is ...
We show that recent high statistics data on skewness and kurtosis ratios of net proton-number distributions, obtained at beam energy \sqrt{s_{_{NN}}}=54.4 \sqrt{s_{_{NN}}}=54.4 GeV, agree well with lattice QCD results on cumulants of net baryon-number fluctuations close to the pseudo-...
