Compute the gradient of the synthetic Cox proportional hazards model

Description

This function calculates the gradient of the synthetic Cox proportional hazards model using a vectorized approach.

Usage

get_cox_syn_gradient(X, time, coefs, hazard_constant)

Arguments

X	A matrix of covariates with rows representing observations and columns representing features.
time	A vector of time-to-event data.
coefs	A vector of regression coefficients.
hazard_constant	A scalar representing the hazard constant.

Value

A numeric vector representing the gradient of the synthetic Cox model.
