Experimental moments of the nucleon structure function F2 [PDF]
, 2006 Experimental data on the F2 structure functions of the proton and deuteron, including recent results from CLAS at Jefferson Lab, have been used to construct their n1 approaching 0, although the precision of the data did not allow to exclude the 1/5 value.

Underestimation of Pearson’s product moment correlation statistic [PDF]
Oecologia, 2018 Pearson's product moment correlation coefficient (more commonly Pearson's r) tends to underestimate correlations that exist in the underlying population. This phenomenon is generally unappreciated in studies of ecology, although a range of corrections are suggested in the statistical literature.

Sufficient statistics for the Pareto distribution parameter
Российский технологический журнал, 2021 The task of estimating the parameters of the Pareto distribution, first of all, of an indicator of this distribution for a given sample, is relevant.

From lattice Quantum Electrodynamics to the distribution of the algebraic areas enclosed by random walks on $Z^2$ [PDF]
, 2016 In the worldline formalism, scalar Quantum Electrodynamics on a 2-dimensional lattice is related to the areas of closed loops on this lattice. We exploit this relationship in order to determine the general structure of the moments of the algebraic areas ...

Journal of Statistical Theory and Applications (JSTA), 2019 In this paper we obtain exact expressions and some recurrence relations satisfied by single and product moments of dual generalized order statistics from exponentiated Rayleigh distribution. These relations are deduced for moments of order statistics and

Instantons and Nucleon Magnetism [PDF]
, 2000 We construct improved QCD sum rules for the nucleon magnetic moments by implementing direct-instanton contributions to the operator product expansion of the nucleon correlator in a magnetic background field.

Recurrence Relations for Single and Product Moments of Dual Generalized Order Statistics from a General Class of Distributions [PDF]
Journal of Statistical Theory and Applications (JSTA), 2015 In this paper we derive some general recurrence relations between single and product moments of dual gener- alized order statistics from a general class of distributions, thus generalizing and unifying the earlier results in this direction due to several

Asymptotic behaviour of the Urbanik semigroup [PDF]
, 2013 We revisit the product convolution semigroup of probability densities e_c(t),c>0 on the positive half-line with moments (n!)^c and determine the asymptotic behaviour of e_c(t) for large and small t>0.
