Histogram (left) and cumulative normalised histogram (right) of the random forest classification probabilities using a bin size of 0.005. 71%, 52% and 81% of the correctly classified galaxies, quasars, and stars have classification probabilities greater than 0.99. Correct classifications must have a probability greater than one third and incorrect classifications must have a probability less than one half. In general correctly classified quasars have lower classification probabilities than correctly classified stars or galaxies.
