This correlation is also confirmed by the results of a linear regression (R 2 = 0.9574, p < 10 −4 ; after removing the elaboration data point: R 2 = 0.8146, p < .0005; note that these correlations do not include the data point elaboration + similarity).
although removing certain types of coherence relations (the same ones as for crossed dependencies, i.e., elaboration and similarity; cf.
