#interpretation of coefficient of cox proportional hazard (cph) with dummy variable drug library(survival) cphb.drug = coxph(Surv(time,status)~drug, data=dat, method="breslow") cphef.drug = coxph(Surv(time,status)~drug, We can not, however, omit other possible relevant explanatory variables from the model on the grounds that we aren't interested in their relationship to the time to event variable. Here, we show predictability of a model with risk-based kinetics of neurodegeneration, whereby neurodegeneration proceeds as probabilistic events depending on the risk. Moreover, the current neurodegeneration model is virtually equivalent to those applied in the survival analysis of the Cox proportional-hazards regression model with time-dependent covariates (see Appendix 2). Cox proportional hazards analysis was used to calculate the adjusted relative hazards of a vascular event by each variable. Hosmer DW, Lemeshow S (1999) Applied Survival Analysis.

The Prentice, Williams, and Peterson gap time model [26 ] was applied to estimate the hazard ratios of first and second CVD events in separate equations. In banking field In the first case, we'll have a model as a function of n+1 variables (time t and n significant variables), while in the other, it will depend only by time (through a method similar to linear regression). Some survival models have been created to produce principally 2 functions: Survival Function S(t), which represents the odds that the event would happen after time t, and Hazard Curve h(t), that describes probability of the phenomenon at time t.
