15-113. Press the function key that corresponds to the type of regression calculation*1 you want toperform.• To perform quadratic regression, for example, press3(X2). This performs the regression calculation anddisplays the results.*2• You can press 5(COPY) here to copy the obtained regression formula to the graphrelation list screen. See “Inputting an Expression of the Form Y=f(x) and Graphing It”(page 15-10) for more information.4. To draw a regression graph, press 6(DRAW).* 1 For information about regression calculation types, see “Selecting the Regression Type”(page 6-16).*2 For information about the meanings of the values that appear on this screen, see“Displaying Regression Calculation Results” (page 6-17) and the regression graphexplanations on pages 6-17 through 6-21.Note• Besides regression graphs, you also can specify your own expressions and graph them. See“Inputting an Expression of the Form Y=f(x) and Graphing It” (page 15-10).u Scrolling and Panning a Plot or Graph ScreenOn the Picture Plot screen, you can use the cursor keys to scroll the XY-coordinate axes up,down, left, and right. Note that the background image is fixed and does not scroll.You also can press K6(g)5(PAN) and pan (grab-and-drag) the XY-coordinate axes.The pan operation is the same as that in the Graph mode (page 5-10).
