This example uses tables from the Input section. In this example, the new patients in the table, CoxPredict Example Input Table lc_new_predictors, are compared with the reference table, but this example uses partition by id. The hazard ratio is calculated only when the patient's id matches the reference id. There are four patients with ids 1 through 4, and they are compared with the rows from the reference table, CoxPredict Example Input Table lc_new_reference, with the same id.
