Özet:
Studies in medicine and biology are often interested in modeling the effect of covariates on an outcome. The outcome of interest is often time-to-event. Examples of this type of outcome include the time of survival after treatment, the time until disease relapse, or the time to multiple chronic conditions such as cardiovascular heart disease and stroke. The first example illustrates the univariate survival data setting, where a patient is at risk of a single event. The cause of interest in this case is death. The second example illustrates the competing risks setting, a patient is at risk of multiple mutually exclusive causes of failure. The competing causes of failure in this case are relapse and death. The third example illustrates the multivariate survival data setting, where a patient simultaneously is at risk of multiple events. The causes of interest in this case are cardiovascular heart disease and stroke. Regression methods are often used to relate these time-to-event outcomes to covariates. Covariates sometimes follow group structure. Examples of group structure include polynomial terms of continuous variable, categorical variables with more than two levels, and continuous or categorical variables with strong correlation between the covariates. Therefore, it is desirable to have a selection method to determine the covariates significantly affecting the outcome while accounting for the group variable structure.
