A Lack-of-Fit Test for Heteroscedastic Regression Models via Cosine-Series Smoothers

In this paper, a test is derived to assess the validity of heteroscedastic nonlinear regression models by a non‐parametric cosine regression method. For order selection, the paper proposes a data‐driven method that uses the parametric null model optimal order. This method yields a test that is asymptotically normally distributed under the null hypothesis and is consistent against any fixed alternative. Simulation studies that test the lack of fit of a generalized linear model are conducted to compare the performance of the proposed test with that of an existing non‐parametric kernel test. A dataset of esterase levels is used to demonstrate the proposed method in practice.     

Double hierarchical generalized linear models (with discussion)

Summary.  We propose a class of double hierarchical generalized linear models in which random effects can be specified for both the mean and dispersion. Heteroscedasticity between clusters can be modelled by introducing random effects in the dispersion model, as is heterogeneity between clusters in the mean model. This class will, among other things, enable models with heavy-tailed distributions to be explored, providing robust estimation against outliers. The h -likelihood provides a unified framework for this new class of models and gives a single algorithm for fitting all members of the class. This algorithm does not require quadrature or prior probabilities.     

Efficiency of a Linear Combination of the Median and the Sample Mean: The Double Truncated Normal Distribution

Abstract.  We characterize all symmetric location models for which a linear combination of the median and the sample mean is an asymptotically efficient estimator of the location parameter. The resulting model can be understood as a symmetrized or double truncated normal distribution. A simple algorithm to estimate the parameters is given and an application is presented.     

Combining coordinates in simultaneous estimation of normal means

The problem of combining coordinates in Stein-type estimators, when simultaneously estimating normal means, is considered. The question of deciding whether to use all coordinates in one combined shrinkage estimator or to separate into groups and use separate shrinkage estimators on each group is considered. A Bayesian viewpoint is (of necessity) taken, and it is shown that the ‘combined’ estimator is, somewhat surprisingly, often superior.

台湾地区行政诉讼简易程序及启示

我国台湾地区行政诉讼简易程序在公正与效率、接近正义基本理念的指导下,已发展成为涵盖管辖法院、适用范围、救济机制及配套便捷规则的一项成熟法律制度。而大陆地区的行政诉讼简易程序初步设立,尚有不足。为此应汲取台湾地区的成功经验与做法,予以适用范围弹性空间,类型细化,简化起诉审理裁判等相关规则,设置上诉或申诉的限制条件,明确误用诉讼程序的处理办法。     

Where are we when we litigiously judge? Politics and aesthetics in Hannah Arendt and Jacques Rancière

ABSTRACT

In contrast to the scenario depicted by Carl Schmitt, contemporary theory has contradicted the “thesis of differentiation” between aesthetics and “the political.” Critical theorists claimed aesthetic analysis’ relevance for grasping aspects of the political realm. And political thought took an “aesthetic turn.” Hannah Arendt and Jacques Rancière have been influential figures in this turn. Their thought offers a clear response to the challenges to the aesthetico-political Schmitt poses. To approach Arendt and Rancière’s responses, this essay proceeds in three parts. The first section analyses Arendt’s reading of the connection between aesthetics and politics. Focusing on a major shift in her perspective on judgement, I argue that her account is influenced by the ungrounded character of politics. The second section thematises the role that the relationship of aesthetics and politics has in Rancière’s work. I claim that his writings might be read as a challenge to Arendt’s attempt to “stabilise” politics by distinguishing it from the social question. Finally, the third section explicitly contrasts Arendt and Rancière’s accounts of the aesthetic-political. I conclude by arguing that their projects are crucial resources for formulating a critical theory that should resist the exceptionalist temptation to conceive “the political” as an incontestable nature.
