Bayesian validation assessment of multivariate computational models

Multivariate model validation is a complex decision-making problem involving comparison of multiple correlated quantities, based upon the available information and prior knowledge. This paper presents a Bayesian risk-based decision method for validation assessment of multivariate predictive models under uncertainty. A generalized likelihood ratio is derived as a quantitative validation metric based on Bayes’ theorem and Gaussian distribution assumption of errors between validation data and model prediction. The multivariate model is then assessed based on the comparison of the likelihood ratio with a Bayesian decision threshold, a function of the decision costs and prior of each hypothesis. The probability density function of the likelihood ratio is constructed using the statistics of multiple response quantities and Monte Carlo simulation. The proposed methodology is implemented in the validation of a transient heat conduction model, using a multivariate data set from experiments. The Bayesian methodology provides a quantitative approach to facilitate rational decisions in multivariate model assessment under uncertainty.

Generalized partially linear varying-coefficient models

Generalized varying-coefficient models are useful extensions of generalized linear models. They arise naturally when investigating how regression coefficients change over different groups characterized by certain covariates such as age. In this paper, we extend these models to generalized partially linear varying-coefficient models, in which some coefficients are constants and the others are functions of certain covariates. Procedures for estimating the linear and non-parametric parts are developed and their associated statistical properties are studied. The methods proposed are illustrated using some simulations and real data analysis.

民族自治地方农村养老问题与对策初探——以黔东南州锦屏县为例

民族自治地方农村养老工作与构建社会主义和谐社会、社会主义新农村建设、“三农”问题等紧密相关，养老工作能否解决好直接影响到农村的社会稳定、社会的和谐发展和“三农”问题的解决。民族自治地方农村经济相对落后、经济发展不平衡、人口分布不均衡、农村老年人口日益增多、农民工大量外出等现实，给传统养老方式带来了历史性的冲击。这要求建立具有时代特色和地方特色的养老方式。本文在进行充分的实地调查、分析黔东南苗族侗族自治州锦屏县农村现行的养老方式现状、养老方式存在问题的基础上，结合当地实际情况和借鉴其他地方的成功养老方式，提出具体可行的对策。
