Table 3. Results of regression analyses for rodentia.
The regression expressions are: Log(dependent variable) = slope X log(independent variable) + intercept.
| Family | Regression type | Independent variable | Dependent variable | Slope | Intercept | R 2 | Number samples |

Notes.
PI(n) means the phylogenetic informed regression method using BayesTraits and the number in parentheses is the estimated value of lambda. AVG means the cohort averaging regression method. Length (mm) is head and body length in millimeters. Mass (g) is body mass in grams. NA means Not Applicable.
