Table 2.

Common calibration and verification statistics for the 20 reconstruction models produced. lm = linear model, NEG = negative predictor, DW = Durbin-Watson test, 1921–60 diff. = mean difference against the instrumental flow data. The LH model used for the final reconstruction is underlined.
