Species present near San Francisco Bay and included in species classifier.

Nobs is the number of passes recorded during the study that were identified as each species. Counts for less abundance species should be interpreted with caution due to uncertainties in the classification method. Remaining columns evaluate the effectiveness of the statistical classifier used to identify species from call data. Nref is the number of passes for each species included in the reference library. P is precision, the fraction of all calls in the testing data set identified as a species that were made by that species, and R is recall, the fraction of all calls in the testing data set made by a species that were identified as that species. Overall species classification accuracy, the fraction of all calls in the testing data set identified correctly, was 84%.
