How does this skill handle the Proportional Hazards assumption?

It includes specific patterns for testing the PH assumption using Schoenfeld residuals (cox.zph) and provides solutions for violations, such as stratified models or time-varying covariates.

Which R packages are supported by this skill?

The skill includes patterns for core packages like survival and survminer, as well as advanced libraries like flexsurv, rstpm2, tidycmprsk, and the tidymodels 'censored' package.

Does it support complex event analysis like competing risks?

Absolutely. It covers Cause-Specific Hazards and Fine-Gray Subdistribution Hazards using cmprsk and tidycmprsk for cases where multiple event types exist.

Can this skill help with plotting survival curves?

Yes, it provides comprehensive snippets for creating high-quality Kaplan-Meier plots, risk tables, and forest plots using the survminer and ggsurvplot frameworks.

Performs comprehensive survival analysis and time-to-event modeling using modern R frameworks and tidy principles.

This skill provides a robust framework for conducting survival analysis within the R ecosystem, offering standardized patterns for a wide range of statistical methods. It enables Claude to implement everything from basic Kaplan-Meier estimations and Cox proportional hazards models to advanced techniques like competing risks, multi-state models, and restricted mean survival time (RMST). With support for visualization libraries like survminer and integration with the tidymodels 'censored' package, this skill is essential for researchers and data scientists performing clinical, longitudinal, or reliability data analysis.
