党的十一届三中全会以来,随着经济改革和统计改革的深入开展,我国在统计调查方法的应用上也有不少改进,做得更加切合实际了。但是,同客观形势的需要比较,还有不少地方有待进一步改进和提高。值此党的十一届三中全会召开十周年之际,对统计调查问题作一回顾与前瞻,并对多种调查方法的结合运用提出一些意见,以进一步改进统计调查工作,看来是有必要的。党的十三大阐述了关于社会主义初级阶段的理论,提出了这一阶段党的基本路线和指导方针,这对于我国统计工作改革和现代化建设具有十分重要的意义。统计调查是统计认识过程的出发点,采取什么方式进行调查,如何搜集资料,如何进行观察,关系到统计事业的面貌,它是建设有中国特色的社会主义现代化统计的一个重要方面。 相似文献

随机化回答模型的探讨/赵俊康在社会调查中,打许多涉及被调查者隐私的问题,如储蓄、收入、吸毒、性关系等等,一般称为社会敏感问题。采用通常的方法对社会敏感问题进行调查,很难取得真实可靠的资料。为此,沃纳(warner)于1965年设计出一种随机化回答模型... 相似文献

一、评价统计调查体系科学性的原则统计调查是根据预定的目地和要求,设计出科学的调查方案,采用合理的调查方法,有组织有计划地对调查对象实施调查,搜集各种统计数据的过程。在统计工作的三个阶段中,统计调查是基础环节,能否得到丰富的、科学准确的统计数据,取决于统计调查工作是否科学、是否切合实际,因此,统计调查是开展统计分析研究、提供统计优质服务的必要的前提条件。统计调查作为整个社会经济统计工作的一个重要组成部分,与一般的社会经济调查有所不同,它主要是采用大量观察的方法对整个社会经济现象进行调查,反映社会经济现象的总体 相似文献

Carrying out an additional investigation to non-response units is an important means to solve omission data problems in statistics investigation. Usually there exist two basic forms: one is repeating inquiries, the other is doing second sampling. However, even additional investigation is employed, non-response problems are unavoidable. Therefore, the adjustment of data is often needed. The paper mainly discusses the problems mentioned above. 相似文献

近年来,随着民意调查的推广,有关主观指标的统计调查,已逐步为社会各方面所接受。本文拟就主观指标的作用、原则及调查统计方法,作一些粗浅的研究。一社会经济现象是客观存在的。我们对客观存在的社会经济现象分别从规模、水平、速度、结构、比例和效益等方面来反映和描述,这就是通常所说的客观指标,同时,人们对客观存在的社会经济现象又各有其不同的主观感受,我们把人们对客观社会经济现象的意愿、态度、满意程度、期望和评价等主观感受用统计指标加以反映和描述,这就是主观指标。 相似文献

A mail survey has been conducted to discover why certain hospital based health professionals did not reply to a previous mail survey. The results will assist in the design of future mail surveys for this group and may have a more general interest and applicability. Two return-inducing techniques have been tested. Other such techniques, reported in the literature but untested in this study, are listed. The observed responses times are reported and some suggestions regarding timing are made. 相似文献

如何解决网络访问固定样本调查的统计推断问题,是大数据背景下网络调查面临的严重挑战。针对此问题,提出将网络访问固定样本的调查样本与概率样本结合,利用倾向得分逆加权和加权组调整构造伪权数来估计目标总体,进一步采用基于有放回概率抽样的Vwr方法、基于广义回归估计的Vgreg方法与Jackknife方法来估计方差,并比较不同方法估计的效果。研究表明:无论概率样本的样本量较大还是较小,本研究所提出的总体均值估计方法效果较好,并且在方差估计中Jackknife方法的估计效果最好。 相似文献

Tail estimates are developed for power law probability distributions with exponential tempering, using a conditional maximum likelihood approach based on the upper-order statistics. Tempered power law distributions are intermediate between heavy power-law tails and Laplace or exponential tails, and are sometimes called “semi-heavy” tailed distributions. The estimation method is demonstrated on simulated data from a tempered stable distribution, and for several data sets from geophysics and finance that show a power law probability tail with some tempering. 相似文献

Often in longitudinal data arising out of epidemiologic studies, measurement error in covariates and/or classification errors in binary responses may be present. The goal of the present work is to develop a random effects logistic regression model that corrects for the classification errors in binary responses and/or measurement error in covariates. The analysis is carried out under a Bayesian set up. Simulation study reveals the effect of ignoring measurement error and/or classification errors on the estimates of the regression coefficients. 相似文献

In this work we propose Bayesian measures to quantify the influence of observations on the structural parameters of the simple measurement error model (MEM). Different influence measures, like those based on q-divergence between posterior distributions and Bayes risk, are studied to evaluate the influence. A strategy based on the perturbation function and MCMC samples is used to compute these measures. The samples from the posterior distributions are obtained by using the Metropolis-Hastings algorithm and assuming specific proper prior distributions. The results are illustrated with an application to a real example modeled with MEM in the literature. 相似文献

Statistical experiments, more commonly referred to as Monte Carlo or simulation studies, are used to study the behavior of statistical methods and measures under controlled situations. Whereas recent computing and methodological advances have permitted increased efficiency in the simulation process, known as variance reduction, such experiments remain limited by their finite nature and hence are subject to uncertainty; when a simulation is run more than once, different results are obtained. However, virtually no emphasis has been placed on reporting the uncertainty, referred to here as Monte Carlo error, associated with simulation results in the published literature, or on justifying the number of replications used. These deserve broader consideration. Here we present a series of simple and practical methods for estimating Monte Carlo error as well as determining the number of replications required to achieve a desired level of accuracy. The issues and methods are demonstrated with two simple examples, one evaluating operating characteristics of the maximum likelihood estimator for the parameters in logistic regression and the other in the context of using the bootstrap to obtain 95% confidence intervals. The results suggest that in many settings, Monte Carlo error may be more substantial than traditionally thought. 相似文献

This paper investigates the block total response method proposed by Raghavarao and Federer for providing accurate estimates of the base rates of sensitive characteristics during surveys. It determines the best balanced incomplete block design to use to estimate the base rates for three, four, five and six sensitive attributes respectively, given a maximum total number of 13 questions. The estimates obtained from this method have smaller variance than estimates obtained using the similar, but more popular, unmatched count technique. 相似文献

Simulation-extrapolation (SIMEX) is a method for correcting for bias in measurement error models, and parametric SIMEX estimates are often used. In this paper, we propose a nonparametric method for computing the SIMEX estimate via the Bezier curve, which is a popular smoothing technique in the computer graphics area. Comparisons are done for the bias of the limit values of parametric SIMEX estimates and the Bezier estimate in the various nonlinear measurement error models. 相似文献

Measurement error is a usually met distortion factor in real-world applications that influences the outcome of a process. In this paper, we examine the effect of measurement error on the ability of the EWMA control chart to detect out-of-control situations. The model used is the one involving linear covariates. We investigate the ability of the EWMA chart in the case of a shift in mean. The effect of taking multiple measurements on each sampled unit and the case of linearly increasing variance are also examined. We prove that, in the case of measurement error, the performance of the chart regarding the mean is significantly affected. 相似文献
