Assessing model fit using diagnostic plots for all speciesAs part of a study, researchers examined the relationship between claw size (propodus height in mm) and its closing force (in Newtons) for three intertidal crab species: Hemigrapsus nudus (HN), Lophopanopeus bellus (LB), and Cancer productus (CP). The raw data can be seen in Display 7.15 (p. 201). The following code will load the data, group it into four different subsets: ALL (all thre...
