H.K. Eichhorn had a lively interest in statistics during his entire
scientific career, and made a number of significant contributions to the
statistical treatment of astrometric problems. In the past decade, a strong
movement has taken place for the reintroduction of Bayesian methods of
statistics back into astronomy, driven by new understandings of the power
of these methods as well as by the adoption of computationally-intensive
simulation methods to the practical solution of Bayesian problems. In this
paper I will discuss how Bayesian methods may be applied to the statistical
discussion of astrometric data, with special reference to several problems
that were of interest to Eichhorn.
