Survival analysis (or duration analysis) is an area of statistics that models and studies the time until an event of interest takes place.

In order to assess if this informal finding is reliable, we may perform a log-rank test via Survival analysis with censoring. Kaplan-Meier curves to estimate the survival function, S(t)! These groups can be Country, OS Type, etc. Now, we want to split this survival curve into multiple groups. It actually has several names. Survival curves show, for each time plotted on the X axis, the portion of all individuals surviving as of that time. Standard errors and 95% CI for the survival function! It is also called ‘ Time to Event Analysis’ as the goal is to predict the time when a specific event is going to occur.It is also known as the time to death analysis or failure time analysis. If an individual is right censored, the respondent does not experience the event of interest before follow-up ends and it is unknown if the event occurs after censoring. survival is lost, e.g. some patients are lost occurs, i.e. Originally the analysis was concerned with time from treatment until death, hence the name, but survival analysis is applicable to many areas as well as mortality.

Luckily, there are many other R packages that build on or extend the survival package, and anyone working in the eld (the author included) can expect to use more packages than just this one. Survival analysis is one of the primary statistical methods for analyzing data on time to an event such as death, heart attack, device failure, etc. of survival analysis, referring to the event of interest as ‘death’ and to the waiting time as ‘survival’ time, but the techniques to be studied have much wider applicability.
