# Create a Future Projection for a Metric

Projections predict values based on calculation settings that you specify. These Future Projections appear on a special Projection View of your Metric Viewer.

On the Metric Editor, you can create one or both of the projections:

• Future Periods:    For a specified number of future periods
• Partial Period:     For the remaining portion of the period, if the Measurement Interval is longer than one day and the Metric supports collecting data for less than a full period; for more information, see Create a Partial Period Projection

## 1. Open the Metric Editor

1. Open the Charting tab
2. Page down to the Projections section

## 2. Define settings for future projection - linear regression

To specify the manner in which a Future projection is calculated using the 'Linear Regression' formula:

1. Set Project Future <Measurement Interval> values field to 'yes'
2. Enter how many weeks (months, quarters, etc.) of Projections to be calculated in the Project Next field
3. Project Future Week Using can be based on either:
• 'Linear Regression' (Default) using the standard statistical calculation
• 'Historical Trends' (see Step 3)

4.     Set Line slope set using last based on how many of last weeks (months, quarters, etc) should be used for calculating future results

Save and publish

### 2.1. Review the Metric Chart

1. Open the Projection View
2. Adjust Time line to display the future
3. Review the projected future values

## 3. Define the Historical Trend Projection

Modify the initial settings:

1. Select 'historical trend' as an option of projecting future <Measurement Interval>
2. Set Base Metric for projection to 'Current Metric'
3. Select a period on which to Replicate trend from the drop-down list
4. Enter the number of prior periods to be used to calculate the Baseline Trend to Avg

Save & publish

### 3.1. Review the Metric Chart

Notice the projected future values displayed are based on historical values rather than linear formula
