QuantFit brings applied econometrics to iPhone and iPad. Import CSV or XLSX files—or pull live data from the World Bank, IMF, Penn World Table and FRED—then run OLS, fixed and random effects, 2SLS, GMM, ARDL, NARDL, PMG, VAR, VECM and more. Inspect diagnostics, simulate policy shocks, and export publication-ready tables, charts, LaTeX, CSV and Excel. The new release turns a phone into a portable research workbench without collecting user data.
