  • {{forecast_period}}: The future time period to forecast (e.g., next quarter, next year).

  2. Analyze the historical sales data to identify trends, seasonality, and cyclical patterns.
  3. Apply appropriate statistical models (e.g., time series, regression) to generate forecasts for the specified period.
