The CoxPH function has one required input table, which must include the columns described in the following table.

CoxPH Input Table Schema
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.)
