The analysis of covariance method, the method of algebraic differences with all possible differences, and the method of weighted parameter prediction are shown analytically to be identical for fitting a site-index equation that can be transformed into a simple linear model. Results of the analysis apply to both anamorphic and polymorphic systems, which are linear in the parameters. For. Sci. 36(2):464-469.
