Table 4 Species-specific confusion matrices depicting classification accuracy from Model-1 as the percentage of correct behavioral assignments for each behavior. Overall classification accuracies are displayed as estimates with 95% confidence intervals in parentheses

From: Hidden Markov models identify major movement modes in accelerometer and magnetometer data from four albatross species
