  • A Probabilistic Approach to Some of Euler's Number Theoretic Identities
    TRANSACTIONS OF THE AMERICAN MATHEMATICAL SOCIETY Volume 350, Number 7, July 1998, Pages 2939{2951 S 0002-9947(98)01969-2 A PROBABILISTIC APPROACH TO SOME OF EULER'S NUMBER THEORETIC IDENTITIES DON RAWLINGS Abstract. Probabilistic proofs and interpretations are given for the q-bino- mial theorem, q-binomial series, two of Euler's fundamental partition identi- ties, and for q-analogs of product expansions for the Riemann zeta and Euler phi functions. The underlying processes involve Bernoulli trials with variable probabilities. Also presented are several variations on the classical derange- ment problem inherent in the distributions considered. 1. Introduction For an integer k 1, the q-shifted factorial of t is defined as ≥ k 1 (t; q) =(1 t)(1 tq) (1 tq − ) : k − − ··· − By convention, (t; q)0 = 1. Using arguments on partitions, Euler showed that k ∞ (2) k ∞ q t i 1 (1) = (1 + tq − ) (q; q) k i=1 kX=0 Y and ∞ k ∞ t i 1 1 (2) = (1 tq − )− (q; q) − k i=1 Xk=0 Y hold formally. Identity (1) follows from the observation that the coefficient of k n k t q − in either the sum or the product is equal to the number of partitions of n k n k into k distinct parts. The coefficient of t q − in either side of (2) is the number of partitions of n with k parts (repetition allowed). For n 0, similar arguments on partitions with bounded parts yield the ≥ k k n k q-Binomial Theorem: (t; q) = ( 1) q(2) t n − k k 0 X≥ and the n + k q-Binomial Series: 1=(t; q) = tk n+1 k k 0 X≥ Received by the editors August 8, 1996 and, in revised form, September 16, 1996.

  • Characterization of Conjugate Priors for Discrete Exponential Families
    Statistica Sinica 11(2001), 409-418 CHARACTERIZATION OF CONJUGATE PRIORS FOR DISCRETE EXPONENTIAL FAMILIES Jine-Phone Chou Academia Sinica, Taipei Abstract: Let X be a nonnegative discrete random variable distributed according to an exponential family with natural parameter θ ∈ Θ. Subject to some regularity we characterize conjugate prior measures on Θ through the property of linear pos- terior expectation of the mean parameter of X : E{E(X|θ)|X = x} = ax + b.We also delineate some necessary conditions for the hyperparameters a and b, and find a necessary and sufficient condition that 0 <a<1. Besides the power series distri- bution with parameter space bounded above (for example, the negative binomial distribution and the logarithmic series distribution) and the Poisson distribution, we apply the result to the log-zeta distribution and all hyper-Poisson distributions. Key words and phrases: Bounded analytic functions, characterization theorems, conjugate priors, discrete exponential families, posterior expectations. 1. Introduction Let X come from an exponential family with natural parameter θ and density xθ−M(θ) dPθ(x)=e dµ(x), (1.1) where µ is a discrete measure with support {x0,x1,...,0 ≤ x0 <x1 <x2 < ···}. Let χ denote the interior of the convex hull of the support of µ,andletΘbe the natural parameter space, i.e., Θ = {θ, eθxdµ(x) < ∞}.Itisobviousthat 0 0 χ =(x0,x )wherex is the least upper bound of {x0,x1,...},andthatΘis convex and unbounded to the left since the xi,i =1, 2,..., are nonnegative.

  • Arxiv:2008.06200V4 [Math.PR] 4 Jun 2021 Characterizing the Zeta
    Characterizing the Zeta Distribution via Continuous Mixtures Jiansheng Dai,* Ziheng Huang,† Michael R. Powers,‡ and Jiaxin Xu§ June 4, 2021 Abstract We offer two novel characterizations of the Zeta distribution: first, as tractable continuous mixtures of Negative Binomial distributions (with fixed shape parameter, r> 0), and second, as a tractable continuous mixture of Poisson distributions. In both the Negative Binomial case for r ∈ [1, ∞) and the Poisson case, the resulting Zeta distributions are identifiable because each mixture can be associated with a unique mixing distribution. In the Negative Binomial case for r ∈ (0, 1), the mixing distributions are quasi-distributions (for which the quasi-probability density function assumes some negative values). Keywords: Zeta distribution; Negative Binomial distribution; Poisson distribution; continuous mixtures; identifiability. 1 Introduction arXiv:2008.06200v4 [math.PR] 4 Jun 2021 As part of an investigation of heavy-tailed discrete distributions1 in insurance and actuarial science (see Dai, Huang, Powers, and Xu, 2021), the authors derived two new characterizations of the Zeta distribution, which form the basis for the present article.

  • Zeros of Zeta Functions and Zeta Distributions on $\Mathbb{R}^D
    RIMS Kôkyûroku Bessatsu B34 (2012), 3948 Zeros of zeta functions and zeta distributions on \mathbb{R}^{d} Dedicated to Profe ssor Makoto Maejima for his retirement By Takahiro Aoyama* and Takashi Nakamura** Abstract The class of zeta distributions is one of the classical classes of probability distributions on \mathbb{R} . For let be the Hurwitz zeta function. Zeros of zeta functions 0<u\leq 1 , $\zeta$(z, u) , z\in \mathbb{C} , are one of the major subjects in number theory due to the Riemann Hypothesis. The Hurwitz zeta function $\zeta$(z, u) has many zeros except in some conditions. In particular, $\zeta$(z, 1) is the Riemann zeta function. Let where and then does not have z= $\sigma$+\mathrm{i}t , $\sigma$>1 t\in \mathbb{R} , $\zeta$(z, 1) zeros. In [8], it is shown that a normalized function f_{ $\sigma$,1}(t) := $\zeta$( $\sigma$+\mathrm{i}t, 1)/ $\zeta$( $\sigma$, 1) is an infinitely divisible characteristic function. The corresponding distributions are called the Riemann zeta distributions on \mathbb{R} and studied in A distribution with [9]. f_{ $\sigma$,u}(t) := $\zeta$( $\sigma$+\mathrm{i}t, u)/ $\zeta$( $\sigma$, u) , as its characteristic function is called the Hurwitz zeta distribution on \mathbb{R} . In 0<u\leq 1 , [7], it is proved that f_{ $\sigma$,1/2}(t)= $\zeta$( $\sigma$+\mathrm{i}t, 1/2)/ $\zeta$( $\sigma$, 1/2) is also an infinitely divisible characteristic function and u=1/2 or 1 are the only cases to be so. Usually, $\zeta$(z, u) is given by the Dirichlet series or, when $\zeta$(z, u) does not have zeros, by the Euler products.

  • The Zeta Distribution Owes Its Name to the Fact That the Function Ζ(S)
    164 Chapter 4 Random Variables The zeta distribution owes its name to the fact that the function 1 s 1 s 1 s ζ(s) = 1 + + + ··· + + ··· 2 3 k is known in mathematical disciplines as the Riemann zeta function (after the German mathematician G. F. B. Riemann). The zeta distribution was used by the Italian economist V. Pareto to describe the distribution of family incomes in a given country. However, it was G. K. Zipf who applied zeta distribution to a wide variety of problems in different areas and, in doing so, popularized its use. 4.9 EXPECTED VALUE OF SUMS OF RANDOM VARIABLES A very important property of expectations is that the expected value of a sum of random variables is equal to the sum of their expectations. In this section, we will prove this result under the assumption that the set of possible values of the proba- bility experiment—that is, the sample space S—is either finite or countably infinite. Although the result is true without this assumption (and a proof is outlined in the theoretical exercises), not only will the assumption simplify the argument, but it will also result in an enlightening proof that will add to our intuition about expectations. So, for the remainder of this section, suppose that the sample space S is either a finite or a countably infinite set. For a random variable X, let X(s) denote the value of X when s ∈ S is the outcome of the experiment. Now, if X and Y are both random variables, then so is their sum.

The methods are classified based on different criterion of discretization. Keywords: Discrete analogue; Reliability function; Hazard rate function; Competing risk; Exponentiated distribution; Maximum entropy; Discrete pearson; T-X method 1. Introduction Sometimes in real life it is difficult or inconvenient to get samples from a continuous distribution. Almost always the observed values are actually discrete because they are measured to only a finite number of decimal places and cannot really constitute all points in a continuum. Even if the measurements are taken on a continuous scale the observations may be recorded in a way making discrete model more appropriate. In some other situation because of precision of measuring instrument or to save space, the continuous variables are measured by the frequencies of non-overlapping class inter- val, whose union constitutes the whole range of random variable, and multinomial law is used to model the situation. In categorical data analysis with econometric approach existence of a continuous un- observed or latent variable underlying an observed categorical variable is presumed. Categorical variable is the observed as different discrete values when the unobserved continuous variable crosses a threshold value.
