开源软件介绍(OpenSource Introduction):Overview
Contains many tools useful for copula modeling in Matlab that do not exist directly in the Statistics and Machine Learning toolbox. Highlights are:
- Smooth empirical copula density estimation via Beta-Kernels for any D>=2.
- Empirical copula function estimation for any D>=2
- Sampling from calculated empirical copula for D>=2
- Clayton/Frank/Gumbel copula PDF and sampling for D>=2
Directory Structure
- algorithms/ - contains the core copula algorithms.
