Survival analysis is a special kind of regression and differs from the conventional regression task as follows: The label is always positive, since you cannot wait a negative amount of time until the event occurs. Even if there were a pure python package available, I would be very careful in using it, in particular I would look at: How often does it get updated. **Survival Analysis** is a branch of statistics focused on the study of time-to-event data, usually called survival times. Bayesian Survival Analysis¶ Author: Austin Rochford. This topic is called reliability theory or reliability analysis in engineering, duration analysis or duration modelling in economics, and event history analysis in sociology. Natural Language Processing (NLP) Using Python. PySurvival is an open source python package for Survival Analysis modeling - the modeling concept used to analyze or predict when an event is likely to happen. Survival analysis is one of the most used algorithms, especially in Pharmaceutical industry. Install Package install.packages("survival") Syntax This package contains the function Surv() which takes the input data as a R formula and creates a survival object among the chosen variables for analysis. There is a statistical technique which can answer business questions as follows: How long will a particular customer remain with your business?
