Multinomial logit (also termed multi-logit) models permit the analysis of the statistical relation between a categorical response variable and a set of explicative variables (called covariates or regressors). Although multinomial logit is widely used in both the social and economic sciences, the interpretation of regression coefficients may be tricky, as the effect of covariates on the probability distribution of the response variable is nonconstant and difficult to quantify. The ternary plots illustrated in this article aim at facilitating the interpretation of regression coefficients and permit the effect of covariates (either singularly or jointly considered) on the probability distribution of the dependent variable to be quantified. Ternary plots can be drawn both for ordered and for unordered categorical dependent variables, when the number of possible outcomes equals three (trinomial response variable); these plots allow not only to represent the covariate effects over the whole parameter space of the dependent variable but also to compare the covariate effects of any given individual profile. The method is illustrated and discussed through analysis of a dataset concerning the transition of master’s graduates of the University of Trento (Italy) from university to employment. 相似文献

Empirical applications of poverty measurement often have to deal with a stochastic weighting variable such as household size.
Within the framework of a bivariate distribution function defined over income and weight, I derive the limiting distributions
of the decomposable poverty measures and of the ordinates of stochastic dominance curves. The poverty line is allowed to depend
on the income distribution. It is shown how the results can be used to test hypotheses concerning changes in poverty. The
inference procedures are briefly illustrated using Belgian data.

Hahn [Hahn, J. (1998). On the role of the propensity score in efficient semiparametric estimation of average treatment effects. Econometrica 66:315-331] derived the semiparametric efficiency bounds for estimating the average treatment effect (ATE) and the average treatment effect on the treated (ATET). The variance of ATET depends on whether the propensity score is known or unknown. Hahn attributes this to “dimension reduction.” In this paper, an alternative explanation is given: Knowledge of the propensity score improves upon the estimation of the distribution of the confounding variables. 相似文献

由于历史和现实的缘故,国民政府十分关注海外华侨尤其南洋华侨的教育,形成了比较完善的华侨教育体系,学校和学生数量呈上升趋势,学生素质也不断提高。然而由于国民政府侨教政策自身固有的弊病,给南洋侨教带来了相当的消极作用,限制了南洋侨教事业的进一步发展。 相似文献

The Measurement of Multidimensional Poverty 总被引:14,自引:0,他引:14
Many authors have insisted on the necessity of defining poverty as a multidimensional concept rather than relying on income or consumption expenditures per capita. Yet, not much has actually been done to include the various dimensions of deprivation into the practical definition and measurement of poverty. Existing attempts along that direction consist of aggregating various attributes into a single index through some arbitrary function and defining a poverty line and associated poverty measures on the basis of that index. This is merely redefining more generally the concept of poverty, which then essentially remains a one dimensional concept. The present paper suggests that an alternative way to take into account the multi-dimensionality of poverty is to specify a poverty line for each dimension of poverty and to consider that a person is poor if he/she falls below at least one of these various lines. The paper then explores how to combine these various poverty lines and associated one-dimensional gaps into multidimensional poverty measures. An application of these measures to the rural population in Brazil is also given with poverty defined on income and education. 相似文献

从部门本位回归到基本理性——对检察机关职权配置的思考 总被引:1,自引:0,他引:1
高一飞 《山西大学学报(哲学社会科学版)》2008,31(6):86-91
目前,我国法学界对检察机关职权配置问题存在着激烈的争论。争论的主要问题有三个。其中,检察机关是否有侦查权是个伪问题,其本质是检察机关行使侦查权时由谁来监督;检察官不是“中立及超然”的司法人员,不应当有对强制措施的批准权;检察官不应当以居高临下的“法律监督者”的身份监督审判程序,而是应当通过程序动议权和上诉权监督审判程序。目前主张维持检察机关职权现状的学者,有严重的部门本位主义,检察权改革应当摒弃部门本位主义。 相似文献
