Detecting narwhal foraging behaviour from accelerometer and depth data using mixed-effects logistic regression

Table 4 Number of training/test set buzzes and median seconds elapsed between buzzes for each whale for in model trained on 80 % first observations of each whale, also includes rate and odds-ratio for observations having a prediction in 2/30-s windows
