Simulation Results for Generalized Gamma Distribution Inequality Measures

Simulation results evaluate a parameter estimation method for the generalized gamma distribution using grouped data. The dataset supports a study that also analyzes US income data for three years and introduces a web-tool for calculating inequality measures. It was authored by Emrah Altun and last updated on 2026-05 -19.

Use Cases

• Evaluating parameter estimation methods for grouped data based on the described simulation study.
• Analyzing income inequality using Gini, Theil, Atkinson, and Pietra indexes as described.
• Testing the generalized gamma distribution as a model for economic data.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• The associated study includes analysis of US income data for three different years.
• A dedicated web-tool (GGIneq) is provided for practical application of the methods.

Limitations

• Dataset is very small at 13.5 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
