The 5-year observed survival rate refers to the percentage of patients who live at least five years after being diagnosed with cancer. Many of these patients live ...

In mathematical statistics, the survival function is one specific form of survivorship curve and plays a basic part in survival analysis. There are various reasons that a species exhibits their particular survivorship curve, but one contributor can be environmental factors that decrease survival.
This is particularly the case in non-life insurance (e.g. the pricing of motor insurance can allow for a large number of risk factors, which requires a correspondingly complex table of expected claim rates). However the expression "life table" normally refers to human survival rates and is not relevant to non-life insurance.
Survival analysis is normally carried out using parametric models, semi-parametric models, non-parametric models to estimate the survival rate in clinical research. However recently Bayesian models [1] are also used to estimate the survival rate due to their ability to handle design and analysis issues in clinical research.
