Survival analysis for predictive maintenance of turbofan engines

Explaining hazards and example implementation. Today we’ll explore survival analysis. A technique I’m eager to try, as I’ve heard and read multiple times it could be a suitable approach for predictive maintenance.

Survival Analysis with Python Tutorial — How, What, When, and Why

Survival Analysis with Python Tutorial — How, What, When, and Why. Diving into survival analysis with Python — a statistical branch used to predict and calculate the expected duration of time for one or more events.

Converting a Probability to Fail Into a Time to Failure Metric

Getting the most out of your Probability to Fail Models. With predictive maintenance problems, there are two common metrics that represent the health of your asset.

Interpreting Cox Proportional Hazards Model Using Colon Dataset in R

Interpreting Cox Proportional Hazards Model Using Colon Dataset in R: Cox proportional hazards model is used to determine significant predictors for outcomes that are time-to-event.

Survival analysis using lifelines in Python

Survival analysis is used for modeling and analyzing survival rate (likely to survive) and hazard rate (likely to die). Survival analysis using lifelines in Python. Here we load a dataset from the lifelines package. I am only looking at 21 observations in my example. The survival analysis dataset contains two columns: T representing durations, and E representing censoring, whether the death has observed or not. Censoring is what makes survival analysis special. There are events you haven’t observed yet but you can’t drop them from your dataset.

Introduction to Survival Analysis

What is the proportion of a population which will survive past a certain time? Of those that survive, at what rate will they die or fail?

Survival Functions 101

Survival Function forms the major part of the survival analysis and helps the analyst in gaining valuable knowledge related to the time-till events.
