Average Hazard Ratio Estimation — ahr_estimation • bonsaiforest

Function to obtain the average hazard ratio.

Usage

ahr_estimation(x_subg, dummy_subg, est_coef, h0, gamma = 1)

x_subg: (matrix)
the matrix with the subgroup covariates.
dummy_subg: (matrix)
the dummy matrix with the subgroup covariates.
est_coef: (matrix)
the estimated coefficients from the fitted model.
h0: (numeric)
the vector with the cumulative baseline hazard.
gamma: (scalar)
numeric value defining the weights to obtain the average hazard ratio. Default is 1 (in this case the average hazard ratio obtained can be interpreted as the odds of concordance).
