CoefficientTable: Specify the name of the table where the function outputs the estimated coefficients of the input parameters.
LinearPredictorTable: Specify the name of the table where the function outputs the product ßX.
FeatureColumns: Specify the names of the input table columns that contain the features of the input parameters.
CategoricalColumns: [Optional] Specify the names of the input table columns that contain categorical predictors. Each categorical_column must also be a feature_column.; Default behavior: The function detects the categorical columns by their SQL data types.

TimeIntervalColumn: Specify the name of the column in input_table that contains the time intervals of the input parameters; that is, end_time - start_time, in any unit of time (for example, years, months, or days).
EventColumn: Specify the name of the column in input_table that contains 1 if the event occurred by end_time and 0 if it did not. (0 represents survival or right-censorship.) The function ignores values other than 1 and 0.
StopThreshold: [Optional] Specify the convergence threshold.; Default: 0.000000001
MaxIterNum: [Optional] Specify the maximum number of iterations that the function runs before finishing, if the convergence threshold has not been met.; Default: 10
Accumulate: [Optional] Specify the names of the columns in input_table that the function copies to linear_predictor_table.
