A backward construction and simulation of correlated Poisson processes

In this paper, we consider a generalisation of the backward simulation method of Duch et al. [New approaches to operational risk modeling. IBM J Res Develop. 2014;58:1–9] to build bivariate Poisson processes with flexible time correlation structures, and to simulate the arrival times of the processes. The proposed backward construction approach uses the Marshall–Olkin bivariate binomial distribution for the conditional law and some well-known families of bivariate copulas for the joint success probability in lieu of the typical conditional independence assumption. The resulting bivariate Poisson process can exhibit various time correlation structures which are commonly observed in real data.     

Estimating function method for product autoregressive models

The first-order product autoregressive (PAR(1)) model introduced by McKenzie in 1982 McKenzie, E. D. (1982). Product autoregression: A time series characterization of the gamma distribution. Journal of Applied Probability 19:463–468. [Google Scholar] did not attract the attention of practitioners due to the unavailability of a proper estimation method. This article proposes an estimating function (EF) method to fill the gap. In particular, we suggest an optimal combination of linear and quadratic EFs to overcome the problem of parameter identification. The procedure is applied to Weibull and Gamma PAR(1) models. Simulation and data analysis show that the proposed method performs better than the existing methods.     

Statistical inference for the Gompertz distribution based on Type-II progressively hybrid censored data

In this article, the statistical inference for the Gompertz distribution based on Type-II progressively hybrid censored data is discussed. The estimation of the parameters for Gompertz distribution is obtained using maximum likelihood method (MLE) and Bayesian method under three different loss functions. We also proved the existence and uniqueness of the MLE. The one-sample Bayesian prediction intervals are obtained. The work is done for different values of the parameters. We apply the Monto Carlo simulation to compare the proposed methods, also an example is discussed to construct the Prediction intervals.     

Recovery of functions from transformed moments: A unified approach

Two approximations recovering the functions from their transformed moments are proposed. The upper bounds for the uniform rate of convergence are derived. In addition, the comparisons of the estimates of the cumulative distribution function and its density function with the empirical distribution and the kernel density estimates are conducted via a simulation study. The plots of recovered functions are presented for several examples as well.     

人际语法隐喻的多维考察——以《唐顿庄园》为例

人际语法隐喻作为语法隐喻的重要组成部分,是人际意义在语气和情态方面的非一致式表达。语言形式不同,则其传达的语言意义也不尽相同。从语用学、社会学、语篇分析等多个维度综合考察人际语法隐喻非常规表达的语言学意义,挖掘其折射出的特殊人际意义,从而探求人际语法隐喻使用的语言学理据。     

网络语言娱乐功能实现方式及其根源研究

在网络言语交际过程中,网络语言娱乐性的表现形式、特点及其制约机制等问题一直是学界关注的话题.为从语言功能视角阐释网络语言娱乐性的实现方式及其根源等问题,运用了比较分析和例证相结合的研究方法,通过比较分析说明网络语言的内涵及其存在形式的双重性特征,介绍了语言娱乐功能的内涵和陈望道先生的“辞趣”思想,通过网络语言在形趣、音趣和意趣方面的例证分析,对“辞趣”理论实质从语言娱乐功能实现角度重新进行了梳理,指出网络语言娱乐功能具体实现的语言结构形式途径,认为网络言语交际中娱乐性的根源来自于社会物质条件和主体内在需求的合力,因为使用了网络媒介,所以才表现出独具特色的网络言语交际形式.

大学生人际交往能力现状的实证分析

采用自编《大学生人际交往能力调查问卷》,对某高校的380名本科生进行施测。结果显示:大学生人际交往能力的总体水平较好;不同性别、独生子女与非独生子女、不同来源地、不同年级、不同专业的大学生人际交往能力存在显著性差异。具体而言,男性大学生在影响力、开放性、包容度和人际结交能力方面均稍好于女性,但在情绪控制、友谊表达、人际理解能力方面,则女性好于男性;独生子女在人际交往能力的很多方面都优于非独生子女;来自大中城市的学生,人际交往能力要优于来自农村的学生;在人际结交能力、包容度方面,理工类学生要强于文科类学生;人际处理能力、人际理解能力随着年级的升高而逐渐提高。     

成都将军的设置及其在治理川西藏区中的作用

清乾隆年间对大小金川土司的用兵结束后,为了加强对康藏及川西藏族的统治,乾隆帝特设成都将军,统辖八旗和绿营,治理川边。成都将军在维护川西藏族地区的稳定、保持川藏大道的畅通、巩固西南边疆的安全等方面均起到了积极的作用。
