Proportional Hazards Analysis of Electronic Component Reliability DataThis paper addresses the challenge of analysing electronic component reliability data arising in diverse environments and applications. Most reliability data has such potential associated explanatory variables, the electronic component reliability ...

Regression AnalysisReproducibility of ResultsCoronary Artery BypassComputer SimulationRisk FactorsIn the lower delta of the Paraná River, at the head of the Río de la Plata estuary (Argentina), we compared net aboveground primary production (NAPP) and soil properties of the dominant macrophyte ...
OBJECTIVE: To investigate the significance of clusterin (CLU) expression as a risk factor for breast cancer through tissue microarray technology and univariate analysis of overall survival. METHODS: Formalin-fixed, paraffin-embedded tissues from 158 cases of breast cancer and 31 cases of normal adjacen...
In each cohort (first stage of the two stage meta-analysis), we used Cox proportional hazards models to estimate the risk of type 2 diabetes comparing type 2 diabetes cases to all other patients without diabetes at the end of follow-up after exploring that the proportional hazards assumption ...
上述生存分析模型,即Kaplan-Meier survival estimate,是单变量分析(univariable analysis),在做单变量分析时,模型只描述了该单变量和生存之间的关系而忽略其他变量的影响。(为什么要考虑multi-variables?比如在比较两组病人拥有和不拥有某种基因型对生存率的影响,但是其中一组的患者年龄较大,所以生存率可能受到基因型 或...
