WebSelect the Best Fit. After fitting all points, the best fit among the set of possible fit is selected by the following rules: \(\lambda_z > 0\) and at the same time the maximum r-squared must be within an adjusted \(r^2\) factor of the best. The adjusted \(r^2\) factor is controlled by PKNCA.options("adj.r.squared.factor") and it defaults to 10^{-4}. ...
