A walk-through of the pre-estimation step — what the app asks for before it lets you run a single regression, and why.

A clear visual explanation of how time series and panel datasets are structured, with regression examples for each.

Logs, differences, lags, growth rates — applied to a series in two taps. The app keeps the original alongside.

Build derived variables from existing columns. Formulas, ratios, and conditional series — without leaving the app.

Fixed effects vs. random effects, side by side, on a real panel. Hausman test included.

Pooled Mean Group ARDL — the long-run common slopes plus heterogeneous short-run dynamics, end to end.
