分层贝叶斯模型下调查计数数据的联合点估计和方差估计

Joint Point and Variance Estimation under a Hierarchical Bayesian model for Survey Count Data

Terrance D. Savitsky, Julie Gershunskaya, Mark Crankshaw

摘要:

我们提出了一个新的贝叶斯框架的联合建模的调查点和方差估计计数数据。该方法结合了诱导的先验分布的建模的真实方差,设置它等于点估计值的生成方差,一个关键属性更容易实现连续数据响应型模型。我们的计数数据模型公式化允许以多个分辨率输入域(例如,州、地区、国家)并且同时以更高分辨率对模型化估计进行基准(例如,状态)到较低分辨率的那些(例如,区域),以一种方式,借用更多的力量,以提高我们的域估计在更高的分辨率。我们进行了一项模拟研究,在域中生成一个单元群体,以生成地面实况统计数据,并与对从群体中提取的样本进行的直接和建模估计进行比较,在这些样本中,我们显示出跨域误差的减少。该模型适用于美国劳工统计局管理的职位空缺和劳动力流动调查中发布的职位空缺变量和其他数据项。

英文摘要:

We propose a novel Bayesian framework for the joint modeling of survey point and variance estimates for count data. The approach incorporates an induced prior distribution on the modeled true variance that sets it equal to the generating variance of the point estimate, a key property more readily achieved for continuous data response type models. Our count data model formulation allows the input of domains at multiple resolutions (e.g., states, regions, nation) and simultaneously benchmarks modeled estimates at higher resolutions (e.g., states) to those at lower resolutions (e.g., regions) in a fashion that borrows more strength to sharpen our domain estimates at higher resolutions. We conduct a simulation study that generates a population of units within domains to produce ground truth statistics to compare to direct and modeled estimates performed on samples taken from the population where we show improved reductions in error across domains. The model is applied to the job openings variable and other data items published in the Job Openings and Labor Turnover Survey administered by the U.S. Bureau of Labor Statistics.
