In survival analysis, the hazard ratio (HR) is the ratio of the hazard rates corresponding to the conditions characterised by two distinct levels of a treatment variable of interest. For example, in a clinical study of a drug, the treated population may die at twice the rate per unit time of the control population. The hazard ratio would be 2, indicating higher hazard of death from the treatment. Webhazard function in the control group can be estimated nonparametrically. However, this requires a large sample size and is diﬃcult to implement and thus is rarely done in practice.
