A Nonparametric Approach to Medical Survival Data: Uncertainty in the Context of Risk in Mortality Analysis
Original language description
Medical survival right-censored data of about 850 patients are evaluated to analyze their uncertainty on one hand and compare two basic surgery techniques in the context with risk of mortality on the other hand. Colorectal data comes from patients who underwent colectomy in the University Hospital of Ostrava. Two basic surgery operating techniques are used for the colectomy: either classical (open) or minimally invasive (laparoscopic). Basic question which arises at the colectomy operation is which typeof operation to choose to guarantee longer overall survival time. Two non-parametric approaches have been used to quantify risk of mortality with uncertainties. In fact, supplement of the risk to one, i.e. survival function with corresponding confidencelevels is calculated and evaluated. First approach considers standard nonparametric estimators resulting from both the Kaplan-Meier estimator of survival function in connection with Greenwood's formula and the Nelson-Aalen estimator of c
