示例1: test_predict_log_hazard_relative_to_mean_without_normalization
# 需要导入模块: from lifelines.estimation import CoxPHFitter [as 别名]
# 或者: from lifelines.estimation.CoxPHFitter import predict_log_hazard_relative_to_mean [as 别名]

assert_frame_equal(log_relative_hazards, np.log(cox.predict_partial_hazard(rossi) / cox.predict_partial_hazard(means).squeeze()))
示例2: test_predict_log_hazard_relative_to_mean_with_normalization
# 需要导入模块: from lifelines.estimation import CoxPHFitter [as 别名]
# 或者: from lifelines.estimation.CoxPHFitter import predict_log_hazard_relative_to_mean [as 别名]
def test_predict_log_hazard_relative_to_mean_with_normalization(self, rossi):
cox = CoxPHFitter(normalize=True)
cox.fit(rossi, 'week', 'arrest')
# they are equal because the data is normalized, so the mean of the covarites is all 0,
# thus exp(beta * 0) == 1, so exp(beta * X)/exp(beta * 0) = exp(beta * X)
assert_frame_equal(cox.predict_log_hazard_relative_to_mean(rossi), np.log(cox.predict_partial_hazard(rossi)))
