What is Survival Analysis Analyze the events that happens within a period of time to answer questions such as: what is the proportion of a population which will survive past a certain time?

Event & Object An event is things that happens within a period of time (ex. Death, or machine malfunction) Event can influence the result of an object’s Survival Analysis Object can be a living organism, machine, or anything that have limited lifetime

Survival Analysis Event and Object will be combined together to form a Model Model analyze object base on the events that happened within a period of time to get the survival rate.

What is Cox Model A model that allows specified factors to influence the rate of a event happening at a particular time, and then evaluate the effects of factors on survival.

Cox Model The rate of event is referred as hazard rate Cox Model separate the events into number of layers depending on the hazard rate Cox Model accurately calculate the survival rate by separating events into layers.
