Econometric Forecasting Framework
Build production-grade econometric forecasts with rigorous diagnostics
What You Can Do
Develop econometric models with proper specification testing, validate all statistical assumptions, and generate point forecasts with confidence intervals and error diagnostics. You'll follow a systematic workflow that catches common pitfalls—autocorrelation, heteroscedasticity, multicollinearity, structural breaks—before your model reaches production. Every forecast comes with documented assumptions, sensitivity analysis, and a reproducible methodology.
Features
Systematically build regression models, compare specifications using information criteria (AIC, BIC), and select the optimal model based on both statistical fit and economic theory.
Automatically test for autocorrelation (Durbin-Watson, Ljung-Box), heteroscedasticity (Breusch-Pagan, White), normality (Shapiro-Wilk), and structural breaks (Chow test, recursive residuals).
Detect equilibrium relationships in multivariate time series using Johansen cointegration tests and vector error correction models (VECM) for long-run dynamics.
Produce point forecasts with confidence intervals, prediction intervals, and fan charts showing forecast uncertainty propagation over multiple periods.
Systematically vary parameters and assumptions to understand how forecasts change under different economic scenarios and stress conditions.
Generate publication-ready methodology sections, data descriptions, assumptions, limitations, and interpretation guidance for each forecast.
Perform out-of-sample validation, compute forecast error metrics (MAE, RMSE, MAPE), and backtest against holdout samples to assess reliability.
Example Output
Example 1: GDP Growth Forecast
Model: Quarterly GDP growth regressed on lagged GDP, unemployment rate, credit growth
Diagnostics:
✓ Durbin-Watson = 2.07 (no autocorrelation)
✓ Breusch-Pagan p-value = 0.43 (homoscedastic)
✓ Normality test p-value = 0.61 (residuals normal)
⚠ Structural break detected at 2008Q4 (Chow test p < 0.001)
Forecast (2026 Q1-Q4):
Q1: 2.3% ± 0.8% (90% CI: 1.2–3.4%)
Q2: 2.1% ± 0.9% (90% CI: 0.8–3.4%)
Q3: 2.0% ± 1.1% (90% CI: 0.4–3.6%)
Q4: 2.2% ± 1.2% (90% CI: 0.4–4.0%)
Example 2: Scenario Analysis
Base Case (above): 2.1% average growth
Downside (unemployment +2%): 1.4% average growth
Upside (credit growth +5%): 2.8% average growth
Sensitivity: A 1pp rise in unemployment reduces GDP growth by 0.35pp
Example 3: Model Comparison
ARIMA(1,1,1): AIC=145.2, RMSE=0.89%
OLS with lagged variables: AIC=142.8, RMSE=0.76% ← Selected
VECM with cointegration: AIC=141.5, RMSE=0.71%
