Notes. The first column represents the predicted class that was determined by considering not only the most probable class, but also the next most likely class. These activity classes are outlined in more detail in Table 3. The second and third columns denote respectively the percentage and count of objects relative to the total population of spectroscopically classified composite galaxies. The fourth and fifth columns represent the same analysis, but for LINER galaxies. For the inconclusive classifications, see Sect. 5.2.
