Observing trends

You use trends to track in what direction the forecasted data moves.

1. Open the forecast for which you want to create a trend.
2. Open a forecast in the Forecast editor.
3. Run the forecast model that you want to test.
   The forecast results are displayed in the Results editor.
4. Click the Create Trend toolbar button.
   A trend graph and a trend table are displayed in the Results editor.
5. Observe the three types of trends in the trend chart to determine if there is a significant trend to the data, and in what direction it moves.

   Local Trend

   The difference between the current value within a period and the value for the last period.

   Global Trend

   The difference between the current value within a period and the average of all values. The period, order, and magnitude of fluctuation between positive and negative values can be used to determine the significance of the linear trend.

   Linear Trend

   The linear regression value for the current period, as displayed in the trend graph.
