合理导向大学生文化消费——北京市大学生文化消费调查分析报告

文化,从广义上讲,是人类社会历史实践过程中所创造的物质财富和精神财富的总和。大学生作为国家建设生力军,精神食粮的吸取是其自我发展与完善的最好途径,文化消费则是获取精神食粮的最直接也是最主要的方式,从这个意义上说,合理的文化消费行为与正确的消费观念是优秀大学生所应具备的素质之一。为此,我们进行了为期四年(2000年——2003年)的连续调查,以探讨当今大学生的文化消费结构、内部联系及其发展趋势,从而引导理性的文化消费。本次调查的范围在北京市各高校展开,依据学校类型,力求涵盖综合性大学以及文、理科大学,选取11所高校为:中…

Inferences from logistic regression models in the presence of small samples,rare events,nonlinearity, and multicollinearity with observational data

The logistic regression model has been widely used in the social and natural sciences and results from studies using this model can have significant policy impacts. Thus, confidence in the reliability of inferences drawn from these models is essential. The robustness of such inferences is dependent on sample size. The purpose of this article is to examine the impact of alternative data sets on the mean estimated bias and efficiency of parameter estimation and inference for the logistic regression model with observational data. A number of simulations are conducted examining the impact of sample size, nonlinear predictors, and multicollinearity on substantive inferences (e.g. odds ratios, marginal effects) when using logistic regression models. Findings suggest that small sample size can negatively affect the quality of parameter estimates and inferences in the presence of rare events, multicollinearity, and nonlinear predictor functions, but marginal effects estimates are relatively more robust to sample size.     

Ethnic differences in the labour market: a comparison of the samples of anonymized records and Labour Force Survey

The public use sample from the 1991 UK census makes it possible to conduct individual level analyses of ethnic minorities' educational and occupational attainments. Unfortunately, however, the census asked only about higher level qualifications obtained after reaching 18 years of age. A comparison with the Labour Force Surveys (LFSs) shows that the census gives in some respects a misleading impression of qualifications among the first-generation members of ethnic minorities: the LFS data show that ethnic minorities tend to be more polarized in their qualifications than the British-born whites, with relatively large proportions at the two extremes, either with degrees or with no qualifications at all. It follows that the census's treatment of qualifications may tend to exaggerate the scale of disadvantage of ethnic minorities in the labour market, and particularly in access to the salariat where qualifications play a particularly large role in recruitment. Regression analyses of sample of anonymized records and LFS data confirm these expectations although they indicate that the results of the census are not seriously misleading as regards the pattern of ethnic disadvantages in the competition to avoid unemployment. The LFS data also confirm earlier findings that the ethnic penalties are in general of similar magnitude among the second generation to those among the first generation, despite the substantial equalization of educational experience that has taken place. There is some evidence that disadvantages in access to the salariat may have been reduced, but this is counterbalanced by the evidence that disadvantages in the avoidance of unemployment may have deteriorated.     

中国家庭养育目标的影响因素及其差异分析

基于2010年中国家庭动态跟踪调查(CFPS)数据库,分析养育目标在城乡之间以及不同少儿年龄组之间的差异,并利用Logistic回归模型探讨家庭养育目标的影响因素。结果表明:养育目标在城乡之间有显著差异,但在不同的少儿年龄组之间无显著差异;父亲职务、父母受教育程度及母亲户口状况不同程度地影响着"在自己年老时得到帮助"、"延续家族香火"、"从经济上帮助家庭"、"使家庭在自己的生活中更重要"和"增加亲属联系"这五个养育目标。     

Finite mixture of regression models for a stratified sample

Despite the popularity and importance, there is limited work on modelling data which come from complex survey design using finite mixture models. In this work, we explored the use of finite mixture regression models when the samples were drawn using a complex survey design. In particular, we considered modelling data collected based on stratified sampling design. We developed a new design-based inference where we integrated sampling weights in the complete-data log-likelihood function. The expectation–maximisation algorithm was developed accordingly. A simulation study was conducted to compare the new methodology with the usual finite mixture of a regression model. The comparison was done using bias-variance components of mean square error. Additionally, a simulation study was conducted to assess the ability of the Bayesian information criterion to select the optimal number of components under the proposed modelling approach. The methodology was implemented on real data with good results.     

A comparison of suicide patterns in Australia and Hong Kong

We analyse the patterns of 6564 suicides in Hong Kong and 23671 suicides in Australia for the period 1981–1993. Within the unifying framework of logistic regression we investigate how suicide rates vary with marital status and age and how these patterns vary over time and between the two cultures. The main significant differences between the two cultures are that rates are higher in Australia, rates for males are much higher than for females in Australia but only slightly higher in Hong Kong, in Hong Kong the oldest age group has the highest suicide rate unlike in Australia and the protective effects of marriage are larger in Australia.     

大数据背景下的线上、线下混合访问调查方法研究

传统的调查方式,特别是入户调查,难度大、周期长、成本高,随着样本需求的增大,传统的调查方式逐渐无法满足研究需要。基于大数据背景下的网络访问固定样本调查能够快速、高效地采集大量、多样性的样本,但却面临着非概率样本在统计推断上缺乏理论支持的挑战。文章利用基于倾向得分的样本匹配方法从网络访问固定样本中抽取与线下概率样本相匹配的样本,与线下概率样本结合产生一个新样本,并重点检验网络访问固定样本与线下样本相混合在统计调查中的可行性。统计检验表明,基于倾向得分的匹配样本近似线下概率样本,匹配样本的调查结果近似线下概率样本的调查结果,在一定条件下网络访问固定样本可以与线下概率样本相混合,近似地替代完全的线下概率样本调查。
