Table 4. Results of allometric analysis for OLS and RMA regression of the 22 cranial skull variables in A. mississippiensis.

For each variables, the R², intercept, slope, lower 95% confidence interval for the slope, upper 95% confidence interval for the slope, scaling category, significance of scaling trend, and the minimum sample size required for 95% of replicates to return a result of allometry.
