论按劳分配与按生产要素分配的有机结合

在社会主义市场经济条件下坚持按劳分配的主体地位,既是社会主义生产过程本身的客观要求,也是社会主义市场经济健康发展的现实要求。同时,由于多种所有制及多元产权主体的存在,作为市场机制在分配领域发挥作用的具体表现,按生产要素分配在社会主义市场经济条件下也具有必然性。实践中,必须在全面认识二者对立统一关系的基础上,从微观经济领域的运行层次和所有制结构层次以及宏现经济运行层次实现按劳分配与按生产要素分配的有机结合。     

试析我国收入分配中的公平问题

收入分配公平是一个历史性范畴,它的内涵随生产关系的变化而变化.正确理解我国收入分配的公平,必须搞清楚机会公平与结果公平、收入分配公平与社会主义市场经济的关系,确立初次分配注重效率,再分配注重结果公平的分配范式.在分配中,防止平均主义,保持合理差距,反对两极分化,坚持效率优先、兼顾公平的原则,促进我国生产力的发展,不断提高人民群众的生活水平.     

On calculating the fisher information in order statistics

This article gives a simple result for the expression of the Fisher information in order statistics. This result enables us to calculate easily the Fisher information in any set of order statistics whose details have been known to be messy and complicated. We consider here its application in the optimal spacing problem where the exact Fisher information in order statistics has been approximated with the asymptotic information or the reciprocal of the variance of a suitable estimator.

Semi-parametric estimation of ROC curves based on binomial regression modelling

This paper presents a method of estimating a receiver operating characteristic (ROC) curve when the underlying diagnostic variable X is continuous and fully observed. The new method is based on modelling the probability of response given X , rather than the distribution of X given response. The method offers advantages in modelling flexibility and computational simplicity. The resulting ROC curve estimates are semi-parametric and can, in principle, take an infinite variety of shapes. Moreover, model selection can be based on standard methods within the binomial regression framework. Statistical accuracy of the curve estimate is provided by a simply implemented bootstrap approach.     

Residual analysis for spatial point processes (with discussion)

Summary.  We define residuals for point process models fitted to spatial point pattern data, and we propose diagnostic plots based on them. The residuals apply to any point process model that has a conditional intensity; the model may exhibit spatial heterogeneity, interpoint interaction and dependence on spatial covariates. Some existing ad hoc methods for model checking (quadrat counts, scan statistic, kernel smoothed intensity and Berman's diagnostic) are recovered as special cases. Diagnostic tools are developed systematically, by using an analogy between our spatial residuals and the usual residuals for (non-spatial) generalized linear models. The conditional intensity λ plays the role of the mean response. This makes it possible to adapt existing knowledge about model validation for generalized linear models to the spatial point process context, giving recommendations for diagnostic plots. A plot of smoothed residuals against spatial location, or against a spatial covariate, is effective in diagnosing spatial trend or co-variate effects. Q – Q -plots of the residuals are effective in diagnosing interpoint interaction.
