Explain how complex contracts can be constructed to help mitigate the moral hazard problem. Explain what is an incomplete market, what is hedging at minimum cost and what is understood by completing a market. Explain insurance and risk. Explain 'spontaneous order' in terms of m...
Hazard ratios (HRs) and 95% confidence intervals for survival curves were calculated using a Cox proportional hazards model. Risk table was included, providing the number of patients at risk at different time points. Full size image We next analyzed potential clinical prognostic power of the HNSCC...
In recent years, the dealing with natural hazards in Switzerland has shifted away from being hazard-oriented towards a risk-based approach. Decreasing soci... T Plattner - 《Natural Hazards & Earth System Sciences》 被引量: 24发表: 2005年 Information systems security engineering: a critical compo...
To provide resources that explore associations of expression with survival, we overlaid meta-information including association of gene expression with hazard ratio (HR) of death (Fig. 5, Supplemental Fig. 13, online). The integration of multiple data sources retained the ability to detect robust ...
For estimation of APP, a novel statistical method applying tests for a constant postoperative hazard was implemented. Multivariable mortality analysis was performed. The APP was determined to last for 80 postoperative days (95% confidence interval 40–100days). Within this period, 55 patients died ...
whereh0(t) is the baseline hazard and\(\psi\)are the regression parameters,\({gi}\)the mutation status of the gene feature,ridenotes the treatment assignment for patienti, such thatri = 0 indicates that the patient received chemotherapy andri = 1 indicates that gefitinib was adminis...
