Treating records as censored in a proportional hazards models

In a proportional hazards model, records that do not experience a failure during the observation time should be treated as censored (sometimes called right-censored).

To treat records as censored:

  1. In the Model view, ensure that Proportional Hazards is selected from the Model pop-up button
  2. Click the Configure button to the right of the Model pop-up button
  3. Check the box labeled "Treat outcome as censored if:"
  4. Use the predicate editor to define censoring conditions

The number of records regarded as censored will appear to the right of the checkbox.

Records may also be censored if a default column is defined; this is useful if censored observations appear in one column, and non-censored observations appear in another column.
