Memory Required:

270 bytes: 174 for program, 96 for data (statistic. registers 48).

Program instructions:

1.Key in the program routines; press †when done.

2.Press Wand select the type of curve you wish to fit by pressing: S for a straight line;

L for a logarithmic curvy.;

E for an exponential curve; or P for a power curve.

3.Key in x–value and press f.

4.Key in y–value and press f.

5.Repeat steps 3 and 4 for each data pair. If you discover that you have made an error after you have pressed fin step 3 (with the &@value prompt still visible), press fagain (displaying the %@value prompt) and press WU to undo (remove) the last data pair. If you discover that you made an error after step 4, press WU. In either case continue at step 3.

6.After all data are keyed in, press WR to see the correlation coefficient, R.

7.Press fto see the regression coefficient B.

8.Press fto see the regression coefficient M.

9. Press

f

to see the

%@

ˆ

 

 

value prompt for the xˆ , y –estimation routine.

10.ff you wish to estimate yˆ based on x, key in x at the %@value prompt, then press fto see yˆ (&@).

11.If you wish to estimate xˆ based on y, press f until you see the &@value prompt, key in y, then press fto see xˆ (%@).

12.For more estimations, go to step 10 or 11.

13.For a new case, go to step 2.
