k k k k k Selecting the Regression Type
After you graph paired-variable statistical data, press 1(CALC). Then you can use the
function menu at the bottom of the display to select from a variety of different types of
regression.
• {2VAR} ... {paired-variable statistical results}
• {X}/{Med}/{X^2}/{X^3}/{X^4}/{Log}/{Exp}/{Pwr}/{Sin}/{Lgst}
... {linear regression}/{Med-Med}/{quadratic regression}/{cubic regression}/{quartic
regression}/{logarithmic regression}/{exponential regression}/{power regression}/

k k k k k Displaying Regression Calculation Results
Whenever you perform a regression calculation, the regression formula parameter (such as
a and b in the linear regression y = ax + b ) calculation results appear on the display. You can
use these to obtain statistical calculation results.
Regression parameters are calculated as soon as you press a function key to select a
regression type, while a graph is on the display.
k k k k k Graphing Statistical Calculation Results
While the parameter calculation result is on the display, you can graph the displayed
regression formula by pressing 6(DRAW).
