groupdiff_tau() computes $$min(x/y, y/x)$$, i.e. the smallest symmetric ratio between $$x$$ and eqny that is smaller than 1. If $$x$$ is a vector, the symmetric ratio between all elements in $$x$$ is computed.

groupdiff_absdiff() computes $$max(abs(x-y, y-x))$$, i.e. the smallest absolute difference between $$x$$ and $$y$$. If $$x$$ is a vector, the symmetric absolute difference between all elements in $$x$$ is computed.

Usage

groupdiff_tau(x)

groupdiff_absdiff(x)

groupdiff_diff(x)
