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.
TargetColumns
Specify the names of the InputTable columns that contain the features of the input parameters.
CategoricalColumns
[Optional] Specify the names of the InputTable columns to treat as categorical predictors. Each categorical_column must also be a feature_column.
For information about columns that you must identify as numeric or categorical, see Identification of Numeric and Categorical Columns.
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 InputTable column 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 InputTable columns that the function copies to linear_predictor_table.
