### Input Data

|                    | Inputs                                                                                                                             |
| ------------------ | ---------------------------------------------------------------------------------------------------------------------------------- |
| **\*Target Data**  | Data Input                                                                                                                         |
| **\*Model Name**   | Name of the user-defined linear/quadratic model                                                                                    |
| **Predict Output** | <p>If not empty, the model will additionally make prediction on <strong>Target Data</strong> and store </p><p>the result here.</p> |
| **Merge Data**     | Predict Output will be created with predicted labels concatenated to Merge Data.                                                   |
| **\*x (numeric)**  | <p>User-selected columns to be x.</p><ul><li>One or more columns should be selected.</li></ul>                                     |
| **\*y (numeric)**  | <p>User-selected columns to be y.</p><ul><li>Only one column should be selected.</li></ul>                                         |
