Argument Category Description
InputTable Required Specifies the name of the input table.
OutputTable Required Specifies the name of the output table.
InputColumns Required Specifies the names of the columns of the input table that contain the response and predictors.

The syntax of predictor_columns is:

{col[,...] | [start_column:end_column]}[,...]

where col is a column name and start_column and end_column are the column indexes of the first and last columns in a range of columns. The range includes start_column and end_column.

The leftmost column has column index 0, the column to its immediate right has column index 1, and so on.

  • In a column range, brackets do not indicate optional elements. You must include the bracket characters (for example, '[2:6]').
  • This function can take at most 799 response and predictor variables.
Method Optional Specifies the method to use for linear regression. The default value is 'lasso'.
Intercept Optional Specifies whether an intercept is included in the model (and not penalized). The default value is 'true'.
Normalize Optional Specifies whether each predictor is standardized to have unit L2 norm. The default value is 'true'.
MaxIterNum Optional Specifies the maximum number of steps the function executes. The default value is 8*min(number_of_predictors, sample_size - intercept). For example, if the number of predictors is 11, the sample size (number of rows in the input table) is 1532, and the intercept is 1, then the default value is 8*min(11, 1532 - 1) = 88.
