ahr_estimation function

Average Hazard Ratio Estimation

Function to obtain the average hazard ratio.

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

Arguments

• 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).

Returns

Average hazard ratio
