Create a chronological dataset
Assemble a dated series, handle missing timestamps and generate lags, rolling statistics and calendar features to expose temporal structure.
Analyse inflation trends. Inspect forecasting errors.
Inflation trend analysis converts time-indexed price signals into short-term forecasts and indicators. Relevant concerns include temporal leakage, seasonality, calendar effects and stable timestamp handling. Productionising this task adds retraining schedules, alerting on data drift and clear forecast-interval communication.

Inflation trend analysis converts time-indexed price signals into short-term forecasts and indicators. Relevant concerns include temporal leakage, seasonality, calendar effects and stable timestamp handling. Productionising this task adds retraining schedules, alerting on data drift and clear forecast-interval communication.
A proposed extension: produce short-horizon inflation forecasts and simple trend indicators for an internal monitoring dashboard. This prototype is a technical demonstration and not suitable for automated financial or policy decisions; a human reviewer should remain in charge.
Assemble a dated series, handle missing timestamps and generate lags, rolling statistics and calendar features to expose temporal structure.
Train a simple regressor on recent lags and rolling means as a reproducible baseline before adding complex models.
Use walk-forward splits or a hold-out tail to measure MAE and inspect forecast residuals for seasonality and structural shifts.
Define retraining cadence, monitor input drift and provide forecast intervals and escalation rules for unexpected behaviour.
The supplied starter generates a synthetic daily series with a linear trend, sinusoidal seasonality and Gaussian noise, creates lag and 7-day rolling features, fits a RandomForestRegressor on the earlier days, predicts the final 30 days, then prints MAE and a small table of actual vs forecast.
model = RandomForestRegressor(n_estimators=300, random_state=42)
model.fit(train[feature_cols], train["value"])
forecast = model.predict(test[feature_cols])
print(PROJECT_NAME)
print("MAE:", round(mean_absolute_error(test["value"], forecast), 3))The starter uses entirely synthetic data created in memory and does not load real economic indicators or official inflation series. It fits one RandomForest model on a single train/test split (no walk-forward validation), provides no forecast intervals, and does not implement a dashboard, drift monitoring, or production-ready data ingestion.
A proposed extension: replace the synthetic series with official CPI or price-index time series, add calendar and event features, schedule retraining, and expose short-term forecasts and uncertainty bands in a small dashboard for analysts.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
