Table 6:
Estimated slopes before and after the thresholds as well as the estimated thresholds from two real data examples. Left: estimates from the Paramecium population growth dataset; right: estimates from the responses of vegetation to grazing dataset. 95% bootstrap confidence intervals estimated from 103 replicates are shown in parentheses.
