The results are displayed in terms of the rank correlation coefficient. The rank correlation is always in the interval [−1, 1] and is invariant under any monotonic increasing transformation of the data.

The Crystal Ball function, named after the Crystal Ball Collaboration (hence the capitalized initial letters), is a probability density function commonly used to model various lossy processes in high-energy physics. It consists of a Gaussian core portion and a power-law low-end tail, below a certain threshold. The function itself and its first derivative are both continuous.
