Beyond Binary Outcomes: A Guide to Survival Analysis for Football Injury Risk
A comprehensive R tutorial on applying Survival Analysis to sports data, moving beyond simple binary classification for injury prediction. This analysis simulates a 25-man football squad over 4 seasons to model the "time-to-event" for non-contact soft tissue injuries. It covers the creation of Kaplan-Meier survival curves, multivariate Cox Proportional Hazards regression, and the interpretation of Hazard Ratios to quantify the cost of workload and squad rotation.
Swiftkey word predictor Presentation
This presentation pitches a data product designed for the Coursera Data Science Capstone. It outlines the development of a next-word prediction algorithm using N-gram modeling and a "Stupid Backoff" strategy. The project demonstrates the full data science pipeline: from exploratory analysis of a 4-million-line corpus (Twitter, News, Blogs) to the deployment of a reactive Shiny application. The focus is on balancing computational speed with predictive accuracy for mobile-first environments.
