A conditional compression distance that unveils insights of the genomic evolution
We describe a compression-based distance for genomic sequences. Instead of
using the usual conjoint information content, as in the classical Normalized
Compression Distance (NCD), it uses the conditional information content. To
compute this Normalized Conditional Compression Distance (NCCD), we need a
normal conditional compressor, that we built using a mixture of static and
dynamic finite-context models. Using this approach, we measured chromosomal
distances between Hominidae primates and also between Muroidea (rat and mouse),
observing several insights of evolution that so far have not been reported in
the literature.Comment: Full version of DCC 2014 paper "A conditional compression distance
