Summary
In this chapter, we discussed three survival analysis models in depth; the Kaplan-Meier, the exponential, and the Cox Proportional Hazards regression models. Using these frameworks, we modeled survival functions and estimated survival probabilities and hazard ratios for various TTE, right-censored studies. For the multivariate case, we used Cox Proportional Hazards regression to model hazard ratios for covariate analysis on dependent variables. For all models, we demonstrated using the confidence intervals for assessing significance, as well as the corresponding p-values. At this point, the reader should be able to confidently identify the scenarios in which each model would outperform the others and appropriately fit and implement that model to obtain the necessary results for strategic success.
