Sampling and interpolation of cumulative distribution functions of Cantor sets in [0, 1]

open access: yesDemonstratio Mathematica, 2021
Cantor sets are constructed from iteratively removing sections of intervals. This process yields a cumulative distribution function (CDF), constructed from the invariant Borel probability measure associated with their iterated function systems.
