Estimate the kappa value for the synthetic Cox proportional hazards model

Description

This function iterative estimates the kappa value for the synthetic Cox proportional hazards model using a vectorized approach for efficiency.

Usage

get_cox_kappa(X, time, status, hazard_constant)

Arguments

X	A matrix of covariates with rows representing observations and columns representing features.
time	A vector of time-to-event data.
status	A vector indicating event occurrence (1 = event, 0 = censored).
hazard_constant	A scalar representing the hazard constant. Defaults to NULL, in which case it's calculated internally.

Value

A numeric value representing the estimated kappa for the synthetic Cox model.
