网友给山东省省长留言(已办理)曹县将有序推进磐石新城施工进度【留言】我是山东省菏泽市曹县磐石街道磐石新城·磐石明珠小区的一名业主,我们小区2014年开建,2015年开始成了烂尾楼,至今近6年了。6年来,经业主多次上访、政府领导的努力,小区于2020年3月终于复工,但是复工一个月以来,每天都是几个人在敷衍了事,大多数楼并没有工人工作,并没有全面复工的景象。

网友给吉林省省长留言(已办理)长春彩云南街天桥力争6月底前完工【留言】您好,去年11月长春市净月区保利香槟北侧的跨南四环天桥开始修建,直到现在仍未完工。东北的施工时间一年只有几个月,希望有关部门尽快复工。现在很多孩子在华岳上学,只能老人帮助接送,他们又不会开车,绕行太费劲了。金色世界湾那边的天桥基本没人走,倒先修好了。请帮帮这些老人和孩子吧。

【留言】您好!位于西青区李七庄街的中医一附院南院区门口的昌凌路、宝通道、鑫通道等均是车来人往且外地进津求医者甚多,然而不可思议的是这里竟无红绿灯,每天上午巨大的车流量把马路、医院门口堵得水泄不通。【回复】您好!接到您留言后,天津市公安局高度重视,责成公安西青分局进行处理。经该局交警支队核实,您反映的问题地点宝通道与昌凌路交口已设计规划交通信号灯,目前正在由管网公司进行建设。先期属地西青开发区交警大队也同李七庄街相关部门进行了调研,建议中医一附院周边道路进行重新渠化设计,并提供了相关方案,后期将由属地李七庄街组织施工并在此处设置临时信号灯。同时,属地西青开发区交警大队将持续加强该问题地点车辆通行情况的治理,规范道路通行秩序,并建立长效机制。

网友给天津市委书记留言(已办理)西青区迎水道延长线计划拓宽道路【留言】您好!西青区迎水道延长线每天拥堵不堪,由西向东奔外环方向二三百米的路程经常拥堵半小时以上。这条道路有红旗农贸市场和水产市场,大车较多,且承载海泰等方向同市区的连接,加之津沧高速收费站修路又承担了部分导流,入外环左转信号灯不科学,且直行方向又与迎水道有一定角度。后续随着万科紫台、联发锦里交付,格调松间入住率提升,该道路将面临更大压力。     

Choosing the link function and accounting for link uncertainty in generalized linear models using Bayes factors

One important component of model selection using generalized linear models (GLM) is the choice of a link function. We propose using approximate Bayes factors to assess the improvement in fit over a GLM with canonical link when a parametric link family is used. The approximate Bayes factors are calculated using the Laplace approximations given in [32], together with a reference set of prior distributions. This methodology can be used to differentiate between different parametric link families, as well as allowing one to jointly select the link family and the independent variables. This involves comparing nonnested models and so standard significance tests cannot be used. The approach also accounts explicitly for uncertainty about the link function. The methods are illustrated using parametric link families studied in [12] for two data sets involving binomial responses.

Inspection errors in link sampling

Results of an investigation into the sensitivity to two types of inspection error of link sampling procedures described by Harischchandra and Srivenkataramana are reported. Relevant compound distributions are derived. Some comparisons with results obtained in a similar investigation for standard double sampling are also given.     

Investigating the link between the Pill and cancer

Does the contraceptive pill increase the risk of cancer? The question has been asked ever since the pill was introduced, and is one that must worry almost every woman in the country. Small wonder that when the results of a long-term study, which began 40 years ago, came out in the autumn it made front-page headlines. As Phil Hannaford explains, answering the question was not straightforward.     

A semiparametric generalized ridge estimator and link with model averaging

In recent years, the suggestion of combining models as an alternative to selecting a single model from a frequentist prospective has been advanced in a number of studies. In this article, we propose a new semiparametric estimator of regression coefficients, which is in the form of a feasible generalized ridge estimator by Hoerl and Kennard (1970b Hoerl, A. E., Kennard, R. W. (1970b). Ridge regression: Application to nonorthogonal problems. Technometrics 12(1):69–82.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) but with different biasing factors. We prove that after reparameterization such that the regressors are orthogonal, the generalized ridge estimator is algebraically identical to the model average estimator. Further, the biasing factors that determine the properties of both the generalized ridge and semiparametric estimators are directly linked to the weights used in model averaging. These are interesting results for the interpretations and applications of both semiparametric and ridge estimators. Furthermore, we demonstrate that these estimators based on model averaging weights can have properties superior to the well-known feasible generalized ridge estimator in a large region of the parameter space. Two empirical examples are presented.     

Univariate and multirater ordinal cumulative link regression with covariate specific cutpoints

The author considers a reparameterized version of the Bayesian ordinal cumulative link regression model as a tool for exploring relationships between covariates and “cutpoint” parameters. The use of this parameterization allows one to fit models using the leapfrog hybrid Monte Carlo method, and to bypass latent variable data augmentation and the slow convergence of the cutpoints which it usually entails. The proposed Gibbs sampler is not model specific and can be easily modified to handle different link functions. The approach is illustrated by considering data from a pediatric radiology study.     

A generalized-moments specification test for the logistic link

The authors consider the problem of testing the validity of the logistic regression model using a random sample. Given the values of the response variable, they observe that the sample actually consists of two independent subsets of observations whose density ratio has a known parametric form when the model is true. They are thus led to propose a generalized-moments specification test in detail. In addition, they show that this test can be derived using Neyman's smooth tests for goodness of fit. They present simulation results and apply the methodology to the analysis of two real data sets.
