TL;DR: In this article, a probabilistic approach to the problem of counting dwarf satellites around host galaxies in databases with limited redshift information was introduced. But the results of the analysis showed that the Milky Way has significantly more satellites than a typical galaxy of its luminosity, which is useful for understanding the larger cosmological context of our home galaxy.
