Do any standard copulas fit well these sampled bivariate data--exhibiting repulsive behavior--having uniform marginals
S. E. --Thanks very much for your detailed comments!

I must admit that for some time I was thinking of copula in its PDF representation rather than the CDF. However, I'm still asking for assistance either in newly constructing a copula PDF with the requested "repulsion" property, or being directed to some "standard" one already exhibiting this property (at least possibly for some particular parameter values, if a family of copulas).

whuber--does this comment extend as well to the pdf, my principal focus of analysis? In any case, I'm interested in models, in which strong repulsion (relatively low values) is shown for x = y, if still not over the entire line.
