Who is this article for?

Trend Profiles Admins who want to define subscriber-level trend profiles. 

Data & Analysis Administrator role required to manage profiles. Reporting authorities, roles, and record access controls restrict data visibility.

Enabling Trend Analysis
A Trend Analysis license allows use of the trend output to analyze trends over time. Depending on your organization's contract, Trend Analysis may not be enabled in your subscriber area. Contact your Technical Account Manager for additional information.

Trending is one of the many available BI visualization options. Create a Trend Analysis report by searching for data and selecting Trend Analysis from the Custom Visualization options.

The Trending Profile determines the evaluation criteria that applies coloring to the Trend report. Administrators with the proper role can create and manage trend profiles. There is no limit to the number of profiles that can be created. All profiles are available to all users. By default, Trending has three profiles:

• Heat Map: The cells of each row in the trend output grid are colored with a gradient between white and red based on their relative size. Administrators can update the coloring scheme for this profile and optionally choose to color the cells based on their relative size amongst all rows.

• Outliers: Each cell is colored either white, yellow, or red based on whether the value of the cell is either an extreme outlier (Red), an outlier (Yellow), or normal (White). Outlier detection is based on the simple box-plot approach where extreme outliers are cells that are beyond one of the outer fences of the baseline data and outlier cells between the inner and outer fences.

• Statistical Process Control (SPC): The SPC profile uses the Shewhart individuals control chart approach to calculate whether a cell's value is in control or not. The SPC profile uses rules to assign violation points based on conditions that may apply to a cell:

  Rule	Points
  Three most recent points are either increasing or decreasing	5
  Two out of the last five values are either two standard deviations above or below the mean	5
  The most recent point is either above or below the control limits	10

Each cell's color is based on the sum of the violation points that it meets.

• Ten or more points: Red
• Between 4 and 10: Yellow
• Otherwise: White
