Survival Analysis can be done in excel too.

The intention of writing this article is to show you all, " how Survival Analysis can be done using simple formulas of excel". Before I proceed further, let me share a formal definition of Survival analysis. "Survival analysis is a collection of statistical procedures for data analysis where the outcome variable of interest is time until an event occurs. The survivor function represents the probability that an individual survives from the time of origin to sometime beyond time, t." Keeping this definition in mind let us now proceed with our objective of implementing Survival Analysis using excel. I am considering a simple Case of the Manufacturing Unit where a bunch of old Machines having high chances of breakdown is chosen for Maintenance.
