Class DistributionSPL

The smoothed power-law (SPL) distribution for the information-based framework that is described in the original paper.

Unlike for DFR, the natural logarithm is used, as it is faster to compute and the original paper does not express any preference to a specific base.

Note

This API is experimental and might change in incompatible ways in the next release.
