商业银行非财务信用风险分析

传统的信用风险评估方法仅仅从贷款企业角度来评价商业银行所面临的信用风险,而且评价企业信用风险时,也集中在贷款企业的财务风险评价上,忽略了银行本身存、贷款结构和风险状况对信用风险的影响,造成了评估主体缺位。作为对众多文献的补充,从贷款企业非财务风险因素、银行风险因素和宏观经济环境风险因素三个方面进行了信用风险因素分析,完善了商业银行信用风险评估指标体系。

Model diagnostics for smoothing spline ANOVA models

The author proposes some simple diagnostics for assessing the necessity of selected terms in smoothing spline ANOVA models. The elimination of practically insignificant terms generally enhances the interpretability of the estimates and sometimes may also have inferential implications. The diagnostics are derived from Kullback‐Leibler geometry and are illustrated in the settings of regression, probability density estimation, and hazard rate estimation.     

Predicting body fat using weight–height indices

While body fat is the most accurate measure of obesity, its measurement requires special equipment that can be costly and time consuming to operate. Attention has thus typically focused on the easier to calculate body mass index (BMI). However, the ability of BMI to accurately identify obesity has been increasingly questioned. This paper focuses attention on whether more general body mass indices are appropriate measures of body fat. Using a data set of body fat, height, and weight measurements, general models are estimated which nest a wide variety of weight–height indices as special cases. In the absence of a race and gender categorisation, the conventional BMI was found to be the appropriate index with which to predict body fat. When such a categorisation was made, however, the BMI was never selected as the appropriate index. In general, predicted female body fat was some 10 kg higher than that of a male of identical build and predicted % body fat was over 11 percentage points higher, but age effects were smaller for females. Considerable racial differences in predicted body fat were found for males, but such differences were less marked for females. The implications of this finding for interpreting recent research on the effect of obesity on health, society, and economic factors are considered.     

产品类型差异下的消费者渠道偏好异质性 ———基于调节定向理论∗

产品类别是消费者行为研究的重要变量,消费者渠道偏好往往因为产品类别的不同而迥异。 消费者购买不同类型产品时的渠道偏好有何不同? 基于调节定向理论,引入产品实用享乐性与风险性,探 究消费者购买不同类型产品时的消费者渠道偏好差异。 围绕产品的实用享乐性、风险性与消费者渠道偏好 的调节定向匹配提出了 4 个假设,运用实验法采集数据,通过对样本数据的多项 Logistic 分析,对假设进行 了检验,并提出企业顾客管理建议,以期为企业根据产品类型区别建设渠道提供决策支持。
