Provides directly interpretable estimated coefficients for four models in connection with the two-group straight line ANCOVA problem: (A) the full model, which requires the fitting of two intercepts and two slopes; (B) a reduced model, which requires the fitting of a single intercept and single slope; (C) a reduced model, which requires the fitting of two separate intercepts and a single, common slope; and (D) a reduced model, which requires the fitting of a single, common intercept and two separate slopes. The summary function provides tests of fit for the (null) hypotheses of: (1) equivalent data sets, (2) equivalent slopes, and (3) equivalent intercepts.
