Cohort Tree

The Cohort Tree allows you to select the cohort to view in the Output Window.

On the left-hand side of the Output window is the Cohort Tree interface. The Cohort Tree interface displays the number of join point models generated for each unique combination of By-Variable values (which is called a cohort). By selecting check boxes in this list, you can display the associated graph and data for that joinpoint model.

Tree List

The Cohort Tree allows you to select which joinpoint model you wish to display for a given cohort. Just select a check box to view the model results for that cohort. Only one item can be selected at a time. Several icons may also be displayed:

This is the Final Selected Model.

This is the selected model for a grouping not chosen.

This cohort does not have any joinpoints to display or has invalid data.

This cohort has been excluded by the user.

Tree Tool Bar

The bar at the top of the Cohort Tree gives you access to navigation and filtering options. The number of cohorts displayed is shown first, followed by a Filter button, and then 2 green arrow buttons. The Filter button will display the Filter Cohorts pop-up window to allows you to configure the display of cohorts in the Cohort Tree. The green arrow buttons will allow you to move through the cohorts that are available.

Filter Cohorts Window

This Filter Cohorts pop-up window allows you to configure the cohorts that are displayed in the Cohort Tree.

Search - When you type text in this box, the Cohort Tree will be filtered to only show cohorts which have this text. Next to this search box, the X button will clear your search.
Cohorts - The check boxes allow you to select the types of cohort you want to display. Your choices are Valid, Invalid (), and Excluded (). The Valid option allows you to pick the types of models to display: All Models, Final Selected Model (), Specific Model. Invalid cohorts are those which could not be processed successfully by Joinpoint. Excluded cohorts are those that you chose to exclude from this session in the Session window.
Restrict Cohorts By - This option allows you to restrict the cohorts that will be displayed by specific By-Var values. A selection window will allow you to pick those values you want to display.
View Multiple Models Simultaneously - This option will allow you to select more than one model for display at the same time. This is useful if you want to compare the graphs of multiple joinpoint models within the same cohort, or even to compare model results from different cohorts. For more information, please see View Multiple Joinpoint Models.
