Summaries are organized by collar brand (Vectronic and Lotek) and by the training or testing group each elk-season belongs to. For final prediction, we censored one Vectronic elk-season from the training set, three Lotek elk-seasons from the Group A testing set, and three Lotek elk-seasons from the Group B testing set due to low fix success
