Table 7. Mean and standard deviation of the average ranks for each method of prediction in ungaged

basins (PUB), regardless of the method used for index‐gage selection.

[The differential gives the Euclidian distance between the (mean, standard devation) couplet of the

map‐correlation and nearest‐neighbor realizations of each method.  These differentials give a sense of

how sensitive each method is to the information content available at the index gage.  Method

abbreviations are in table 1.]
