The List Editor App

How do I view a list of residuals?

To view a list of residuals, follow these steps.

When the TI-84 Evo graphing calculator calculates a regression model, the residuals are automatically stored in a list named RESID.
To display the residuals in a list, the list can be added to the list editor.

Example: To view the RESID list:

  1. Press m 1.
  2. Press the right arrow key to an empty list. Then press the up arrow key to highlight the list name at the top of the list and press =.
  3. Press a È to open the List Editor.
  4. Press the right arrow key to select :RESID (usually stored as option 7, but named lists are stored alphabetically).
  5. Press = to store LRESID into the empty list. The residuals from the most recent regression calculation will fill the list.
