A copula is the representation of a multivariate distribution. Copulas are used to model multivariate data in many fields.

determine the agents' attitudes toward the potential use of
geotextiles in agriculture, specifically in soil erosion control.
A questionnaire was...

The Late Neogene Deschutes Formation of Central Oregon preserves a remarkable record of heightened pyroclastic activity during...
