Regression Calculations
Regression calculations are realized in LR mode. LR will
appear on the LCD screen when in this mode.
Before realizing regression operations, the table memory
must be deleted by pressing the button followed by
the button and fi nally pressing the button in order
to save the changes.
Individual data is entered as x and y
Multiple data with the same value can be entered by press-
ing the button repeatedly. This operation can be real-
ized by introducing the x value and the y value
followed by a value that represents the number
of times that you wish this data to be repeated. Press the
button.
If the x value is the only one that will be repeated, press the
button, the y value or , value of Y
followed by the a value that represents the num-
ber of times you wish this data to be repeated. Press the
button in order to save the changes.
Regression
The following formulas are used in order to calculate the
constant term “A” and the B regression coeffi cient for the
formula y=A + Bx
