This project will develop a general set of tools for understanding and checking the fit of multilevel models. The new tools include computations of average predictive effects for models with nonlinearity, interactions, and variance components, and generalization of simulation-based model checking for multilevel models. In parallel, multilevel models will be explored for public opinion and voting data. A central application area of this project is to use national poll data to estimate time trends in public opinion for different states, a problem that cannot be solved by existing approaches using state and national polls separately. A related area of work is to model dependence structures among individual voters; that is, voter-level models that can add up districts, states, and the country to predict realistic group-level opinion patterns. This has implications for voting power and also is related to studies of networks in probability theory and sociology.This project is anticipated to have broader impacts in two ways. First, the diagnostic methods for multilevel models will be relevant to a wide range of researchers in social science and survey sampling. Second, the modeling of public opinion and voting patterns will be relevant to studies of state-level opinion trends (an important topic in this modern era of geographically-polarized voting) and for understanding the quantitative relationships between opinion and voting.

这个项目将开发一套通用的工具，用于理解和检查多级模型的适合性。新工具包括计算具有非线性、相互作用和方差分量的模型的平均预测效果，以及对多水平模型进行基于模拟的模型检验。同时，将探索民意和投票数据的多层次模型。该项目的一个主要应用领域是使用全国民调数据来估计不同州民意的时间趋势，这是一个现有方法无法解决的问题，现有方法分别使用州民调和全国民调。一个相关的工作领域是对个人选民中的依赖结构进行建模；也就是，选民级别的模型可以将地区、州和国家相加，以预测现实的小组级别的意见模式。这对投票权有影响，也与概率论和社会学中的网络研究有关。该项目预计将在两个方面产生更广泛的影响。首先，多水平模型的诊断方法将与社会科学和调查抽样调查的广泛研究人员相关。其次，公众意见和投票模式的建模将与州一级意见趋势的研究相关(在这个投票地理两极分化的现代时代是一个重要的主题)，并有助于理解意见和投票之间的数量关系。
