Calculating posteriors in r
Web1 day ago · Q: I would like to use R to generate a histogram which has bars of variable bin width with each bar having an equal number of counts. For example, if the bin limits are the quartiles, each bar would represent 1/4 of the total probability in the distribution. WebApr 13, 2024 · The posterior probabilities from the ensemble classifier (Fig. 8) also add to our confidence in the machine learning prediction given that the majority of the teeth return high posteriors in favour of the assigned class, with the second-highest class posterior in each case also indicating maniraptoran affinities.
