Program Instructions:
1. Key in the program routines; press {c\ when done.
2. Press IXEQI and select the type of curve you wish to fit by
pressing:
• S for a straight line;
• L for a logarithmic curve;
• E for an exponential curve; or
• P for a power curve.
3. Key in x-value and press IR/S I.
4. Key in y-value and press IR/s I.
5. Repeat steps 3 and 4 for each data pair. If you discover that you
have made an error after you have pressed Ir/s Iin step 3 (with
the Y?va/t/e prompt still visible), press Ir/s Iagain (displaying the
X?va/ue prompt) and press Ixeq IU to undo (remove) the last data
pair. If you discover that you made an error after step 4, press
IXEQI U. In either case continue at step 3.
6. After all data are keyed in, press Ixeq I R to see the correlation
coefficient, R.
7. Press IR/SI to see the regression coefficient B.
8. Press IR/SI to see the regression coefficient M.
9. Press IR/SI to see the X?va/ue prompt for the x-, y-estimation
routine.
10. If you wish to estimate y based on x, key in x at the x?value
prompt, then press IR/s I to see y (Y?).
11. If you wish to estimate x based on y, press IR/SIuntil you see the
Y?va/t/e prompt, key in y, then press IR/SI to see x (X?).
12. For more estimations, go to steps 10 or 11.
13. For a new case, go to step 2.
