Asymptotic expansions of moments and cumulants
Many parameters may be expanded as series with terms involving products of expectations and their estimates expanded as series involving products of averages. The computation of moments and cu-mulants of such estimates may be organized if the terms of the series expansions of parameters, estimates and their moments are considered as functions applied to lists. The lists form a vectors space ass...
متن کاملGeneralized moments and cumulants for samples of fixed multiplicity.
Factorial moments and cumulants are usually defined with respect to the unconditioned Poisson process. Conditioning a sample by selecting events of a given overall multiplicity N necessarily introduces correlations. By means of Edgeworth expansions, we derive generalized cumulants which define correlations with respect to an arbitrary process rather than just the Poisson case. The results are a...
متن کاملinvestigating the translation expectancy norms of iranian college student readership in terms of english fiction in persian
مفهوم هنجار برای اولین بار توسط دانشمندی به نام گیدون توری در اواخر دهه 70 مطرح شد. هنجارها توسط محققان مختلفی طبقه بندی شده اند؛ نوع هنجاری که در این تحقیق مورد بحث است "هنجار انتظارات" است. مطالعات ترجمه یک رشته ی نوپا و مستقل است که هنوز به رشد کامل خود نرسیده و بسیاری از شاخه های آن نیاز به پژوهش دارند. یکی ازاین حوزه ها که نیاز به پژوهش دارند، هنجارهای ترجمه هستند به ویژه هنجارهای انتظارات...
Generalized bit- moments and cumulants based on discrete derivative
We give a simple recipe based on the use of discrete derivative, to obtain generalized bit-moments obeying nonadditive statistics of Tsallis. The generalized bit-cumulants may be of two kinds, first which preserve the standard relations between moments and cumulants of a distribution, and are nonadditive with respect to independent subsystems. The second kind do not preserve usual moment-cumula...
متن کاملAn umbral setting for cumulants and factorial moments
We provide an algebraic setting for cumulants and factorial moments through the classical umbral calculus. Main tools are the compositional inverse of the unity umbra, connected with the logarithmic power series, and a new umbra here introduced, the singleton umbra. Various formulae are given expressing cumulants, factorial moments and central moments by umbral functions.
