The CoxPH function has one required input table, which must include the columns described in the following table.
|Column Name||Data Type||Description|
|time_interval_column||SMALLINT or INTEGER||Contains the time interval of the input data; that is, end_time - start_time, in any unit of time (for example, years, months, or days).|
|event_column||SMALLINT or INTEGER||Contains 1 if the event occurred by end_time and 0 otherwise. (0 represents survival or right-censorship.)|
|feature_column||SMALLINT, INTEGER, BIGINT, NUMERIC, or DOUBLE PRECISION||Contains a feature of the input data.
The table must have one such column for each column specified by the FeatureColumns argument. (The CategoricalColumns argument can also specify a feature_column as a categorical_column.)
