3D Age-Specific Mortality Trajectory: A Survival Analysis Protocol.

Three-dimensional age-specific mortality trajectory features the rate of aging and risk for mortality of a population with respect to time (t) and age (x). Demographic and clinical records of patients are key elements to the assessment of interventional outcomes during survival analysis. Herein, a step-by-step protocol shows the retrieval of parametric estimations from both conventional and modified maximum likelihood estimation (MLE) to determine mortality trajectory of hematopoietic stem cells transplant (HSCT) patients characterized by their treatment type.
