 The code of `corkendall` from this package was incorporated into StatsBase on 8 February 2021 (issue [634](https://github.com/JuliaStats/StatsBase.jl/issues/634), commit [647](https://github.com/JuliaStats/StatsBase.jl/commit/11ac5b596405367b3217d3d962e22523fef9bb0d)).
 With further changes, `corkendall` is again a candidate to be incorporated into StatsBase.

+- The function is now multi-threaded. On a PC with 12 cores, it's about 14 times faster than the StatsBase version.
+- There is now a `skipmissing` keyword argument to control the treatment of missing values, along the lines of the `skipmissing` argument to `StatsBase.pairwise`.
