PROPORTIONAL HAZARD MODELS Meaning and Definition

  1. Proportional hazard models, also known as Cox regression models or Cox proportional hazard models, are statistical models used in survival analysis to examine the relationship between covariates and the time to an event. These models are particularly useful when analyzing the time it takes for an event of interest, such as death or disease occurrence, to happen in a population.

    The fundamental assumption of proportional hazard models is that the hazard, or risk of experiencing the event, is proportional across different levels of a covariate. This means that the hazard ratio, which represents the relative risk of the event occurring in one group compared to another, remains constant over time. This assumption allows for the estimation of the effect of covariates on the hazard rate without specifying the baseline hazard function.

    Proportional hazard models utilize the Cox regression technique, which is based on the partial likelihood method. This method allows for the incorporation of both time-dependent and time-independent covariates in the model, enabling the examination of their impact on the hazard rate. The resulting hazard ratio estimates provide valuable information about the strength and direction of the association between the covariate and the event of interest.

    Proportional hazard models are widely used in various fields, including medical research, epidemiology, and social sciences, to elucidate the factors influencing event occurrence. By considering the ratio of hazards, these models provide a flexible approach to analyze survival data without relying on assumptions about the shape of the underlying hazard function.
