Estimating optimal step-function approximations to instantaneous hazard rates
We investigate the problem of estimating the best binary decision tree approximation to the baseline hazard function in the Cox proportional hazards model. Our motivation is to find an effective way of condensing key functional information in the baseline hazard into a small number of estimable parameters. The parameters consist of a threshold and two hazard levels, one to the left of the thres...
متن کاملOPTIMAL DESIGN OF SHELLS WITH STEP-FUNCTION DISTRIBUTION OF THICKNESS
The paper is concerned with a methodology of optimal design of shells of minimum weight with strength, stability and strain constraints. Stress and strain state of the shell is determined by Galerkin method in the mixed finite element formulation within the geometrically nonlinear theory. The analysis of the effectiveness of different optimization algorithms to solve the set problem is given. T...
متن کاملWeb Tool for Estimating the Cancer Hazard Rates in Aging
A computational approach for estimating the overall, population, and individual cancer hazard rates was developed. The population rates characterize a risk of getting cancer of a specific site/type, occurring within an age-specific group of individuals from a specified population during a distinct time period. The individual rates characterize an analogous risk but only for the individuals susc...
متن کاملDecision trees for instantaneous hazard rates with adjustment for covariate effects
We investigate the problem of finding confidence sets for a threshold in the baseline hazard function of the Cox proportional hazards model. The aim is to find an effective way of condensing information in the baseline into a small number of estimable parameters. A binary decision tree is used as a working model, with the jump point (threshold) representing a time at which baseline risk changes...
متن کاملEstimating a smooth baseline hazard function for the Cox model
The aim of fitting a Cox model to time-to-event data is to estimate the effect of covariates on the baseline hazard function. The baseline hazard function, not itself estimated within the model, is the hazard function obtained when all covariate are set to zero. In several applications, it is important to have an explicit, preferably smooth, estimate of the baseline hazard function, or more gen...
