Checking functional form of covariates in cox regression

In this tutorial, you’ll learn how to check the functional form of covariates in Cox regression using Stata. We demonstrate how to use Martingale residual plots and other diagnostic tools to verify whether covariates should be modeled linearly, categorized, or transformed. This step is crucial to ensure a valid model specification in survival analysis. #CoxRegression #SurvivalAnalysis #StataTutorial #DataAnalysis
