Table 3. Best linear regression models for estimating PMFI/FR-total scarred trees/plots, including estimators in Table 2 plus measures of sample size, based on the 96-case calibration dataset.
Only cases where sample-size variables were significant are shown here, otherwise the best models are in Table 2.
