A new distribution with flexible hazard rate function is introduced which is called new modified Burr XII (NMBXII) distribution. The proposed distribution is derived from the T-X family technique and compounding the generalized Nadarajah–Haghighi (GNH) and gamma distributions. We highlighted the shapes of NMBXII density and failure rate functions. The density function of NMBXII model can take shapes such as J, reverse J, positively skewed and symmetrical.  The proposed model can produce almost all types of failure rates such as increasing, decreasing, increasing-decreasing, decreasing-increasing, bimodal, inverted bathtub and modified bathtub. To show the importance of the proposed distribution, we established various mathematical properties such as quantiles, moments, incomplete moments, inequality measures, residual life functions and reliability measures theoretically.  We have characterized the NMBXII distribution via two techniques. We addressed the maximum likelihood estimation technique for model parameters. The precision of the MLEs is estimated via a simulation study. We have considered three real data sets for applications to demonstrate the potentiality and utility of the NMBXII model. Then, we have established empirically that the proposed model is suitable for tax revenue, time periods between successive earthquakes and flood discharges applications. Finally, various model selection criteria, the goodness of fit statistics and graphical tools were used to examine the adequacy of the NMBXII distribution. 
介绍了一种具有柔性危险率函数的新分布,称为新修正的Burr XII(NMBXII)分布。所提出的分布是从T-X族技术导出的,并将广义Nadrajah–Hagheii(GNH)分布和伽玛分布组合在一起。我们强调了NMBXII密度和故障率函数的形状。NMBXII模型的密度函数可以具有J、反向J、正偏斜和对称等形状。所提出的模型可以产生几乎所有类型的故障率,如增加、减少、增加-减少、减少-增加、双峰、倒置浴缸和改良浴缸。为了证明所提出的分布的重要性,我们从理论上建立了各种数学性质,如分位数、矩、不完全矩、不等式测度、剩余寿命函数和可靠性测度。我们通过两种技术对NMBXII分布进行了表征。我们讨论了模型参数的最大似然估计技术。MLE的精度是通过模拟研究来估计的。我们考虑了三个实际的应用数据集,以证明NMBXII模型的潜力和实用性。然后,我们根据经验证明,所提出的模型适用于税收、连续地震之间的时间段和洪水排放的应用。最后,使用各种模型选择标准、拟合优度统计和图形工具来检验NMBXII分布的充分性。

Obeid and Kadry (2019) tried to study the product and quotient of the independent Pareto and Rayleigh random variables. The distributions they obtained are incorrect and in fact there is no closed form distributions as discussed here. We will mention the errors made and try to establish the correct versions of the probability density functions of these distributions for the truncated Pareto and Rayleigh random variables.

The Kumaraswamy distribution is an important probability distribution used to model several hydrological problems as well as various natural phenomena whose process values are bounded on both sides. In this paper, we introduce a new family of inverse Kumaraswamy distribution and then explore its statistical properties. Conventional maximum likelihood estimators are considered for the parameters of this distribution and estimation based on dual generalized order statistics is outlined. A particular sub-model of this family; namely, the inverse Kumaraswamy- Weibull distribution is considered and some of its statistical properties are obtained. Estimation efficiency is numerically evaluated via a simulation study and two real-data applications of the proposed distribution are provided as well.

Estimation of unknown parameters using different loss functions encompasses a major area in the decision theory. Specifically, distance loss functions are preferable as it measures the discrepancies between two probability density functions from the same family indexed by different parameters. In this article, Hellinger distance loss function is considered for scale parameter λ of two-parameter Rayleigh distribution. After simplifications, form of loss is obtained and that is meaningful if parameter is not large and Bayes estimate of λ is calculated under that loss function. So, the Bayes estimate may be termed as ‘Pseudo Bayes estimate’ with respect to the actual Hellinger distance loss function as it is obtained using approximations to actual loss. To compare the performance of the estimator under these loss functions, we also consider weighted squared error loss function (WSELF) which is usually used for the estimation of the scale parameter. An extensive simulation   is carried out to study the behaviour of the Bayes estimators under the three different loss functions, i.e. simplified, actual and WSE loss functions. From the numericalresults it is found that the estimators perform well under the Hellinger distance loss function in comparison with the traditionally used WSELF. Also, we demonstrate the methodology by analyzing two real-life datasets.
利用不同的损失函数估计未知参数是决策理论的一个重要研究领域。具体来说,距离损失函数更可取,因为它测量了由不同参数索引的同一族的两个概率密度函数之间的差异。本文考虑了双参数瑞利分布尺度参数λ的Hellinger距离损失函数。简化后得到了损失的形式,当参数不大时,在该损失函数下计算λ的贝叶斯估计是有意义的。因此,对于实际的海灵格距离损失函数,贝叶斯估计可以称为“伪贝叶斯估计”,因为它是使用对实际损失的近似获得的。为了比较估计器在这些损失函数下的性能,我们还考虑了通常用于估计尺度参数的加权平方误差损失函数(WSELF)。进行了广泛的仿真,研究了三种不同损失函数(即简化损失函数、实际损失函数和WSE损失函数)下Bayes估计量的行为。数值结果表明,与传统的WSELF相比,该估计器在Hellinger距离损失函数下表现良好。此外,我们通过分析两个现实生活中的数据集来演示该方法。

In this paper, a new generalization of one parameter Lindely distribution is proposed. The new distribution is a mixture distribution of Gamma distributions with fixed scale parameter and variable shape parameter. The distribution is called 'GOLD Distribution' as it is a generalization for several distributions such as exponential, Lindely, Sujatha, Amarendra, Devya and Shambhu distributions. The probability density and cumulative density functions are derived. Also, the statistical properties of the GOLD distribution are discussed. Parameter estimation using the maximum likelihood and the method of moments are given. Moreover, an illustration of the usefulness of the GOLD distribution in survival data analysis is discussed based on a real lifetime data.

This paper presents a result of research about the student’s radical intention related to their tolerance and personality type. This research was a collaboration between Statistics, Psychology, and Politics. The main research variable that is radical intention has a psychological construct that is theoretically built with a social approach and political point of view. As a big country, Indonesia has various pluralism i.e ethnic and religion, so that it requires a high tolerance attitude to live in a harmony. Students as the next generation and important elements in society are expected to avoid intolerance. The research subjects were 175 students from an Islamic university in Indonesia. The data were analyzed with Ordinal Regression which intention of radicalism (ordinal) as the dependent variable, personality type (nominal), and tolerance attitude level (ordinal) as independent variables. The majority of these students have good moral values so they can tolerate the difference. From the regression analysis, the type personality and tolerance attitude have a significant effect on radicalism intention.
本文介绍了一个关于学生™激进倾向与他们的宽容度和性格类型有关。这项研究是统计学、心理学和政治学的合作。激进意图这一主要研究变量具有一种从社会方法和政治观点理论上构建的心理结构。印尼作为一个大国,有着多种多样的民族和宗教,因此需要高度宽容的态度才能和睦相处。学生作为下一代和社会中的重要分子,应该避免不容忍。研究对象是来自印度尼西亚一所伊斯兰大学的175名学生。以激进化意向(序数)为因变量,人格类型(标称)和容忍态度水平(序数)作为自变量,采用序数回归分析数据。这些学生中的大多数都有良好的道德价值观,因此他们能够容忍这种差异。回归分析表明,类型人格和宽容态度对激进主义倾向有显著影响。

Comparison of Infinite Capacity FM/FEk/1 Queuing Performance Using Fuzzy Queuing Model and Intuitionistic Fuzzy Queuing Model with Erlang Service Rates 基于模糊排队模型和基于Erlang服务率的直觉模糊排队模型的无限容量FM/FEk/1排队性能比较

In this work, we suggest an analytic technique with triangular fuzzy and triangular intuitionistic fuzzy numbers to compute the membership functions of considerable state-executing proportion in Erlang service models. The inter-entry rate, which is Poisson, and the admin (service) rate, which is Erlang, are both fuzzy-natured in this case, with FEk designating the Erlang probabilistic deviation with k exponentially phase. The numeric antecedents are shown to validate the model's plausibility, FM/FEk/1. A contextual inquiry is also carried out, comparing individual fuzzy figures. Intuitionistic fuzzy queueing models that are comprehensible are more categorical than fuzzy queueing models. Expanding the fuzzy queuing model to an intuitionistic fuzzy environment can boost the implementation of the queuing model. The purpose of this study is to assess the performance of a single server Erlang queuing model with infinite capacity using fuzzy queuing theory and intuitionistic fuzzy queuing theory. The fuzzy queuing theory model's performance evaluations are reported as a range of outcomes, but the intuitionistic fuzzy queuing theory model provides a myriad of values. In this context, the arrival and the service rate are both triangular and intuitionistic triangular fuzzy numbers. An assessment is made to find evaluation criteria using a design protocol in which fuzzy values are kept as they are and not made into crisp values, and two statistical problems are solved to understand the existence of the method.
在这项工作中,我们提出了一种三角模糊和三角直觉模糊数的分析技术来计算Erlang服务模型中相当大的状态执行比例的隶属函数。在这种情况下,进入间率(即泊松)和管理(服务)率(即Erlang)都是模糊性质的,其中FEk表示Erlang与k指数阶段的概率偏差。数值前因式FM/FEk/1验证了模型的合理性。上下文调查也进行,比较个别模糊数字。直觉模糊排队模型比模糊排队模型更具有可理解性。将模糊排队模型扩展到直观的模糊环境可以促进排队模型的实现。本研究的目的是利用模糊排队理论和直觉模糊排队理论来评估具有无限容量的单服务器Erlang排队模型的性能。模糊排队论模型的绩效评价报告为一系列结果,而直觉模糊排队论模型提供了无数的值。在这种情况下,到达率和服务率都是三角模糊数和直觉三角模糊数。采用一种保持模糊值不变而不使其变为清晰值的设计方案,对评价标准进行了评估,并解决了两个统计问题,以理解该方法的存在性。

The inter-entry rate, which is Poisson, and the admin (service) rate, which is Erlang, are both fuzzy-natured in this case, with FEk designating the Erlang probabilistic deviation with k exponentially phase. The numeric antecedents are shown to validate the model's plausibility, FM/FEk/1. A contextual inquiry is also carried out, comparing individual fuzzy figures. Intuitionistic fuzzy queueing models that are comprehensible are more categorical than fuzzy queueing models. Expanding the fuzzy queuing model to an intuitionistic fuzzy environment can boost the implementation of the queuing model. The purpose of this study is to assess the performance of a single server Erlang queuing model with infinite capacity using fuzzy queuing theory and intuitionistic fuzzy queuing theory. The fuzzy queuing theory model's performance evaluations are reported as a range of outcomes, but the intuitionistic fuzzy queuing theory model provides a myriad of values. In this context, the arrival and the service rate are both triangular and intuitionistic triangular fuzzy numbers. An assessment is made to find evaluation criteria using a design protocol in which fuzzy values are kept as they are and not made into crisp values, and two statistical problems are solved to understand the existence of the method.","PeriodicalId":19973,"journal":{"name":"Pakistan Journal of Statistics and Operation Research","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47643007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we introduce a new generalized family of Esscher transformed Laplace distribution, namely the Kumaraswamy Esscher transformed Laplace distribution. We study the various properties of the distribution including the survival function, hazard rate function, cumulative hazard rate function and reverse hazard rate function. The parameters of the distribution are estimated using the maximum likelihood method of estimation. A real application of this distribution on breaking stress of carbon fibres is also considered. Further, we introduce and study the exponentiated and transmuted exponentiated Kumaraswamy Esscher transformed Laplace distributions.
