A copula is a multivariate distribution with uniform marginal distributions. Copulas are mostly used to represent or to model the structure of dependence between random variables, separately from the marginal distributions.

Do any standard copulas fit well these sampled bivariate data--exhibiting repulsive behavior...
Corollary 1 in marginalinvariance]) that the ratio of Q1 to q1 constitutes a sample from a (symmetric) bivariate copula (alternatively termed "permutons or doubly-stochastic measures" WikiCopula) $f(x, … A Gaussian copula with uniform marginals over [0,1] would be quite appealing conceptually--due to the wide range of applicability of multivariate normal distributions. …

What are examples of symmetric copulas $f(x,y)=f(y,x)$ having relative minima for $f(x,x)$?
That is, based on my study BlochRadiiRepulsion, I believe that I am dealing with a symmetric copula $f(x,y)=f(y,x)$ defined over the unit square for which the values of $f(x,x)$ assume relative minima …

Is a bivariate copula relevant in this physics setting manifesting uniform univariate margin...
Our question here is whether it is suitable--and how--to search in this setting for a bivariate copula having these two marginal uniform distributions. … This finding led us to the question what--if any--is the pertinent bivariate copula having this pair of uniform marginals. …
