عالمى معاشى افكار اور اسلامى معاشى فكر

This article aims to present a concise overview regarding global economic ideas and its historical development with brief evaluation of capitalism and communism as well as question of laissez-faire and concept of ownership in relation to Islamic economic thought. What are the rudiments, fundamentals and historical sketch of these systems? Measuring them analytically vis-à-vis their comparative examination has been taken into account to visit the characteristics of prevailing as well as outdated and nonoperational economic systems. As capitalism emphasis on eagerness to find wealth where billionaires are about to getting more and more ignoring various other ethical perspectives and paying no attention to the poor classes of society. Communism claiming equality remained also not compatible to sustain around the globe as a balanced and stable system. At the end this article predicts that other than Islamic economic thought no system may fulfill the natural need of global economy and it also recommends that Islamic Scholars have to present an alternative full-fledged practical model for economics.

Some New Families of Continuous Distributions Generated from Burr Xii Logit

This thesis is based on six chapters. In these chapters five new families of distributions are introduced by using the Burr XII distribution. In Chapter 1, a brief introduction of the existing families of distribution, the objectives and organization of this thesis are presented. In Chapter 2, Generalized Burr G family of distributions is proposed by using the function of cdf − log[1 − G(x)]. In Chapter 3, Marshall-Olkin Burr G family of distributions is introduced by using odd Burr G family of distributions used as generator proposed by Alizadeh et al. (2017). In chapter 4, odd Burr G Poisson family of distribution is introduced by compounding odd Burr G family with zero truncated Poisson distribution. In Chapter 5, a new generalized Burr distribution based on the quantile function following the method given by Aljarrah et al. (2014). In Chapter 6, Kumaraswamy odd Burr G family of distributions is introduced using odd Burr G family as a generator. The mathematical properties of these families are obtained, such as asymptotes and shapes, infinite mixture representation of the densities of the families, rth moment, sth incomplete moment, moment generating function, mean deviations, reliability and stochastic ordering, two entropies, Renyi and Shannon entropies. The explicit expression of distribution ith order statistic is also obtained in terms of linear combination of baseline densities and probability weighted moments. Model parameters are estimated by using the maximum likelihood (ML) method for complete and censored samples. Special models are given for each family, their plots of density and hazard rate functions are displayed. One special model for each family is investigated in detail. Simulation studies are also carried out to assess the validity of ML estimates of the model discussed in detail. Application on real life data is done to check the performance of the proposed families.
