Table 2. Overall results of polynomial regressions.
Order | R2 | F-test | P-value |
---|---|---|---|
1st | 0.797 | 86.477 | <0.001 |
2nd | 0.855 | 62.032 | <0.001 |
3rd | 0.856 | 39.504 | <0.001 |
The strengths of correlations between models and response variables are represented as R2 values. F-test simultaneously accesses multiple coefficients of regression and compares the fits of different linear models. The P-values stand for the statistical significance of corresponding F-test.
