A statistical approach to coronavirus classification based on nucleotide distributions
The objective of this study is to analyze specific genomes, namely the RNA of coronaviruses, based on the parameters obtained from the distributions of nucleotide sequences in their RNA. The viral RNA was subjected to distribution based on nucleotide sequences obtained by changing one nucleotide base (adenine) into a "whitespace", with empty sequences denoted as "x". Statistical spectra were constructed in such cases. They exhibited three distinct peaks that were consistent across the studied species. Parameters based on the rank–frequency distributions of the obtai
