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 W and 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 f in step 3 (with the &@value prompt still visible), press f again (displaying the %@value prompt) and press W U to undo (remove) the last data pair. If you discover that you made an error after step 4, press W U. In either case continue at step 3. 6. After all data are keyed in, press W R to see the correlation coefficient, R. 7. Press f to see the regression coefficient B. 8. Press f to see the regression coefficient M. 9. Press f to see the %@value prompt for the xˆ , yˆ -estimation routine. 10.ff you wish to estimate yˆ based on x, key in x at the %@value prompt, then press f to 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 f to see xˆ (%@). 12. For more estimations, go to step 10 or 11. 13. For a new case, go to step 2.
