Notes. In the first two columns: least-squares estimates of the regression coefficients and their errors; third column: t-statistic for the tests of the statistical significance of the covariates. In the last column is reported the physical impact of the variation Δpi of the various inputs. All the p-values of the tests are <2 × 10-16. The residual standard error σ and the squared multiple correlation coefficient R2 are reported in the last row.
