Frequency distributions of ${\Xi }_{ML}\left({\Phi }_{4n}^{\left(l\right)}\left(x_k\right)|g,\omega ,\mu ,\sigma ,1\right)$ estimates (${\mu }_1$ and ${\sigma }_1$). Query (l) $\in$ CTSD (class = 4). (a) CTSD-ESR, (b) CTSD-VDR, (c) CTSD-COX2, and (d) CTSD-CTSD. * The color bars (right side of the distribution) indicate frequency (e.g., yellow in 3(a) represents 3500 to 4000 queries, the mean of the ML estimates varied from 0.45 to 0.5 and their standard deviation varied from 0.08 to 0.1 in the standard).
