Starting Simple

The first step for any Driver Model is to set up the required Numeric nodes. They will provide the constant values, values that we will be able to change when we go to the Research Grid.

The two constant values that we have for this driver model are the:

  • Monthly repayments; and
  • Loan amount.

To set up these nodes:

  1. Drag two numeric nodes onto the workspace.
  2. Set the value of the first one to 160000.
  3. Rename this node Loan Amount.
  4. Set the second node to 736.
  5. Rename this node to Repayment Amount.
  6. For both nodes make sure that the box labelled Publish to Results has been ticked (this can be found by going to the properties of the nodes).
