§ iii the workspace

One page, the whole pipeline.

Data, specification, fit, diagnostics, and export — in the same quiet cream page. Nothing opens a new modal unless you asked for it.

§ ii output
Journal-style results

Results that read like a paper.

Standard errors in parentheses. Significance stars by journal convention (Newey-West, cluster-robust, or bootstrapped — your choice). Tabular numerics throughout.

Export directly to LaTeX (booktabs), typeset PDF, or Word. Every run writes a reproducibility hash alongside the coefficient vector.

  • ✓LaTeX, PDF, and Word export
  • ✓Robust and cluster-robust SE by default
  • ✓Pre-registered significance conventions
  • ✓Reproducibility hash on every fit

§ iv for researchers

Built for
applied econometrics.

QuantFit is designed for empirical researchers, PhD students, policy analysts, and economists working with macroeconomic, financial, trade, development, and panel data.
What is available now
  • 1.Import your own CSV or XLSX data, or pull public economic series inside the app.
  • 2.Estimate cross-section, panel, time-series, cointegration, and dynamic-panel models.
  • 3.Inspect coefficient tables, confidence intervals, and method-specific diagnostics.
  • 4.Export tables, charts, and reproducibility scripts for the next stage of your workflow.

No invented endorsements: evaluate QuantFit from its documented methods, screenshots, and working App Store build.
