    2. Train the computer software or forecasting algorithm using the past values
    3. Use the forecasting algorithm to make future observations
  • Trend Analysis Method: Also known as “Time Series Analysis,” this forecast method uses past data to predict future events, excluding outliers and holding more recent data in higher regard.
    This method is most effective when there is a large quantity of historical data showing clear and stable trends.
This book is about the statistical methods and models that can be used to produce short-term forecasts. Our objective is to provide an intermediate- level
