Abstract

This study models survival times in pediatric patients following bone marrow transplantation by comparing several modeling approaches. We analyze time-to-event data using the semi-parametric Cox proportional hazards model, as well as fully parametric exponential, log-logistic, and generalized gamma models. The model performance is assessed using the Akaike information criterion and the concordance index.
