Triple exponential smoothing with trend and seasonality components. Generates 5-year forecasts with 95% confidence intervals — computed in-browser, no API call.
Holt-Winters double exponential smoothing with confidence bands
Configure parameters and click Run Forecast
Pearson correlation matrix computed across multiple economic indicators for any country. Heatmap reveals which forces move together — and which diverge.
Choose 3–6 indicators for the correlation matrix
Pearson r · Range: −1 (inverse) to +1 (direct)
Select indicators and click Compute Matrix
Z-score and IQR fence methods identify statistically significant deviations — economic shocks, crises, and structural breaks — flagged directly on the time series.
Red markers indicate statistically significant deviations
Configure parameters and click Detect Anomalies
Side-by-side comparison of up to 5 countries across any indicator. Overlaid time series reveals divergence, convergence, and structural differences.
Normalised to index (first year = 100) for comparability
Add countries and click Compare
