<p>The title says it all, I read a paper which cites this mean, I looked in the provided reference but didn't saw any mathematica formula for the mean. Is anyone aware of it</p>

There is no formula for the [Pryor & Meylan (1993)](https://ui.adsabs.harvard.edu/abs/1993ASPC...50..357P/abstract) mean. Equations 2 and 3 in the reference paper have to be solved through some sort of iterative scheme.
