 Since our primary target is maintainability and readability of the implementation, we have not considered the efficiency and the performance of the code yet. However, a (limited in scope) benchmark on Clayton's `pdf` shows competitive behavior of our implementation w.r.t `DatagenCopulaBased.jl` (but not `BivariateCopulas.jl`). To perform this test we use the [`BenchmarkTools.jl`](https://github.com/JuliaCI/BenchmarkTools.jl) [@BenchmarkTools] package and generate 10^6 samples for Clayton copulas of dimensions 2, 5, 10 with parameter 0.8. The execution times (in seconds) are given below:
