long_data.RdThis dataset contains information about individual observations across multiple time points, including survival-related variables such as survival_time and survival_status. The data also includes markers (marker_1,marker_2, marker_3), and other covariates (Z_1,Z_2).

A covariate representing a numeric value (e.g., biomarker or age).
A covariate representing another numeric value (e.g., another biomarker or variable).
A numeric value representing the first marker at the given time point.
A numeric value representing the second marker at the given time point.
A numeric value representing the third marker at the given time point.
The survival time (in years, months, or other units) for the individual.
The survival status (1 = event, 0 = censored) indicating whether the individual experienced the event (e.g., death).
