Newton-Raphson optimization

I am currently working on my research, namely comparing the conventional optimization method, namely Newton-Raphson, in estimating Coxph parameters with the SGD optimization method. What if I want to use Newton Raphson as an optimizer on Coxph? Please help me

The issue does not identify a file, test, or entry point. Start by locating the CoxPH implementation and its current SGD optimization path, then determine how an alternative Newton-Raphson optimizer would fit. Done would require a defined implementation scope and tests or documented comparison showing Newton-Raphson parameter estimation works.
