Explicit expressions for the directed likelihood statistic, r, and two modified directed likelihood statistics, r* and r(dagger), are given for several standard hypotheses on concentrations in von Mises-Fisher distributions, and for several standard hypotheses on mean directions in von Mises distributions.
