Intriguing yet simple skewness - kurtosis relation in economic and demographic data distributions; pointing to preferential attachment processes. (arXiv:1807.06911v1 [stat.AP])
来源于:arXiv
In this paper, we propose that relations between high order moments of data
distributions, for example between the skewness (S) and kurtosis (K), allow to
point to theoretical models with understandable structural parameters. The
illustrative data concerns two cases: (i) the distribution of income taxes and
(ii) that of inhabitants, after aggregation over each city in each province of
Italy in 2011. Moreover, from the rank-size relationship, for either S or K, in
both cases, it is shown that one obtains the parameters of the underlying
(hypothetical) modeling distribution: in the present cases, the 2-parameter
Beta function, - itself related to the Yule-Simon distribution function, whence
suggesting a growth model based on the preferential attachment process. 查看全文>>
