A matrix containing sum of squared residuals, sum of pure error, F-statistic and
This function performs lack-of-fit test on regression residuals. This test
assumes, that overall residual error should not be significantly larger than
error within groups with the same x (replicates). It is called by 'summary'
methods, but also can be called directly by user.
