  1. On the Linear Scoring dialog box, click RESULTS.
  2. Click data (note that the RESULTS tab is disabled until after the analysis is completed).
    Linear Scoring > Results > Data

    Results data, if any, is displayed in a data grid.

    If a table was created, a sample of rows is displayed here - the size determined by the setting specified by Maximum result rows to display in Tools > Preferences > Limits.

    The following table is built in the requested Output Database by Linear Regression scoring. Note that the options selected affect the structure of the table. Those columns in bold below comprise the Unique Primary Index (UPI). Also, there may be repeated groups of columns, and that some columns are generated only if specific options are selected.

    Output Database table (Built by Linear Regression scoring)
    Name Data Type Description
    Key User Defined One or more unique-key columns which default to the index defined in the table to be scored (i.e., in Selected Tables). The data type defaults to the same as the scored table, but can be changed via Primary Index Columns.
    <app_var> User Defined One or more columns as selected under Retain Columns.
    <dep_var>

    (Default)

    FLOAT The predicted value of the dependent variable. The name used defaults to the Dependent Variable specified when the model was built. If Use Dependent variable for predicted value column name is not selected, then an appropriate column name must be entered here.
    Residual

    (Default)

    FLOAT

    The residual values of the evaluation, the difference between the estimated value and the actual value of the dependent variable. This is generated only if the Evaluate or Evaluate and Score options are selected. The name defaults to “Residual” unless it is overwritten by the user.
