Crash Course: Copulas – Theory & Hands-On Project with R

Master Copula Theory, Visualization, Estimation, Simulation, and Probability Calculations with the copula Package in R

What you'll learn
- Understand the fundamentals of copulas – Learn what copulas are, their mathematical properties, and their role in modeling dependence structures
- Explore Sklar’s Theorem – Understand how joint cumulative distribution functions (CDFs) decompose into marginal distributions and a copula function
- Learn different types of copulas – Study Gaussian, t-Student, Clayton, and Gumbel copulas and their characteristics
- Estimate copula parameters in R – Use the copula package to estimate copula parameters through statistical methods
- Perform goodness-of-fit tests – Assess the quality of fitted copula models using statistical criteria such as AIC, BIC, and log-likelihood
- Visualize copulas in R – Generate contour plots, 3D surfaces, and scatter plots to interpret dependence structures
- Simulate data using copulas – Use copulas to generate synthetic datasets that preserve the dependence structure of modeled data
- Analyze dependencies – Compute Kendall’s Tau, Spearman’s Rho, and tail dependence coefficients to measure both typical and extreme event correlations

Requirements
- Basic understanding of probability and statistics – Familiarity with concepts such as probability density functions (PDFs), cumulative distribution functions (CDFs), joint, marginal, and conditional distributions, as well as correlation.

- Familiarity with mathematical functions and their characteristics.
- Willingness to work with mathematical formulas and apply them in R.
- Ability to install and use R and RStudio on a computer.
- Access to a computer with an internet connection to download necessary packages.
- Introductory experience with R programming – Including data import, working with basic functions, and handling variables.
- Curiosity and motivation to learn copula theory and its applications.
- Patience and persistence to analyze dependencies between variables and apply copula-based techniques.
