Cox Regression builds a predictive model for time-to-event data. The model produces a survival function that predicts the probability that the event of interest has occurred at a given time t for given values of the predictor variables. The shape of the survival function and the regression coefficients for the predictors are estimated from observed subjects; the model can then be applied to new cases that have measurements for the predictor variables. lvs> I therefore defined a time-dependent covariate as a function of the time lvs> surviving.

Abstract The Cox proportional-hazards regression model has achieved widespread use in the analysis of time-to-event data with censoring and covariates.

The main idea is: COMPUTE T_COV = Sum ( Boolean(i) * Variable(i) ) .

Time-dependent Cox models are more appropriate for external covariates (e.g., external covariates vary as a function of time, independent of the failure time) and are considered in this paper. In a slightly comparable situation, a covariate is measured at baseline but its effect on the outcome is not constant over the follow-up time, which is a violation of the proportional hazards assumption In this article, we propose an approach to deal with such survival‐time‐dependent covariate missingness based on the well known Cox proportional hazard model.
