Static panel models

Configure and estimate fixed-effects and random-effects specifications, with panel structure treated as part of the model rather than an afterthought.

  • Fixed effects
  • Random effects
  • Instrumental-variable workflows

Dynamic heterogeneous panels

Work with pooled mean group, mean group, dynamic fixed effects, CS-ARDL, and common-correlated-effects approaches documented in the app.

  • PMG and MG
  • Dynamic fixed effects
  • Cross-sectional augmentation

Dynamic GMM

QuantFit documents Arellano–Bond difference GMM and Blundell–Bond system GMM workflows, including common specification and diagnostic choices.

Useful for applied research

The app is aimed at economists working with macroeconomic, finance, trade, development, and policy panels who want a portable complement to their desktop workflow.
