Save this program under the name POLYR, to emphasize calculation of the
correlation coefficient r.
Using the POLYR program for values of p between 2 and 6 produce the
following table of values of the correlation coefficient, r, and the sum of square
errors, SSE:
While the correlation coefficient is very close to 1.0 for all values of p in the
table, the values of SSE vary widely. The smallest value of SSE corresponds to p
= 4. Thus, you could select the preferred polynomial data fitting for the
original x-y data as:
p
