Calculating and Graphing Paired-Variable Statistical Data
Execute the calculation and produce sine regression analysis results.
Display a sine regression graph based on the analysis results.

P.6 While the statistical data list is on the display, recall the set up screen to specify a
list ("List 1" through "List 6") for "Resid List". Calculated residual data is stored in
the specified list.
The vertical distance from the plots to the regression model will be stored.
Plots that are higher than the regression model are positive, while those that are
lower are negative.
Residual calculation can be performed and saved for all regression models.
Any data already existing in the selected list is cleared. The residual of each plot is
stored in the same precedence as the data used as the model.
