Panel Data Toolbox for MATLAB

Panel Data Toolbox for MATLAB provides econometric routines for analysis of balanced and unbalanced panel data, implementing estimation methods, instrumental-variable panels, spatial panel models, and model tests to support rigorous econometric inference in MATLAB.

Key Features:

• Estimation Methods: Implements fixed effects, between effects, and random effects models for panel data, supporting both balanced and unbalanced panels.
• Instrumental Variables (IV) Panels: Implements instrumental-variable methods for panel data to address endogeneity from omitted variables or measurement error.
• Spatial Panel Models: Implements a range of spatial panel models to capture spatial or proximity-based dependencies across panels.
• Relevant Tests: Provides tests for fixed effects, random effects, and diagnostic procedures for model validation.
• Validation: Performs numerical checks of results against other commercial and free software packages.

Scientific Applications:

• Panel econometrics: Estimation and inference of individual heterogeneity and effects in balanced and unbalanced panel datasets.
• Endogeneity correction: Identification and estimation of causal effects in panel data using instrumental variables.
• Spatial dependence analysis: Modeling and inference for datasets with geographic or proximity-based correlations across panels.
• Model validation and diagnostics: Testing fixed and random effects and applying diagnostics to assess model assumptions.

Methodology:

Implements fixed effects, between effects, and random effects estimators; instrumental-variable methods for panels; spatial panel model formulations; tests for fixed effects, random effects, and diagnostics; and numerical validation via comparisons with other commercial and free software packages.
