The problem of poverty is the most important problem that many developing countries suffer from. Poverty has many negative effects to social, political and economic life in a society. These problems have always been the major concerns to policy makers. The decision makers try to construct some plans and economic reforms to decrease poverty all around the… (More)
Poverty measures are used to measure poverty levels or degrees of poverty in a population. Stochastic dominance refers to a set of relations between distributions. Stochastic dominance orders of poverty measures have been discussed by many authors in the literature. In this paper, definition of stochastic dominance is introduced and used to order poverty… (More)
Poverty measures are used to measure poverty levels or degrees of poverty in a population. In this talk, we investigate the estimation of poverty measures using both truncated log-normal and truncated gamma distributions. For Comparisons and illustrations, Our results are applied to the real data sets collected in Egypt between 1995/1996 and 2008/2009.
In traditional statistics, we process crisp data – usually, results of measurements and/or observations. Not all the knowledge comes from measurements and observations. In many real-life situations , in addition to the results of measurements and observations, we have expert estimates, estimates that are often formulated in terms of natural language, like "… (More)
Let µ be a self-similar measure on R generated by an equicon-tractive iterated function system. We prove that the Hausdorff dimension of µ * n tends to 1 as n tends to infinity, where µ * n denotes the n-fold convolution of µ. Similar results hold for the L q dimension and the entropy dimension of µ * n .
In this paper, we propose a natural model describing competition between two research groups of the same average research strength. The analysis of this model enables us to conclude that a more diverse group has an advantage: namely, the more diverse the group, the higher the average quality of its publications.
—To properly gauge the extent of poverty in a country or in a region, economists use semi-heuristic poverty measures such as the Foster-Greer-Thorbecke (FGT) metric. These measures are used because it was empirically shown that they capture the commonsense meaning of the extent of poverty better than previously proposed measures. However, the fact that… (More)
