Create Filters Using the Filter Editor
You can create filters
By clicking the toolbar button
By selecting Tools > Filters
Alternatively, by selecting an existing Filter List view by clicking in it, then pressing Insert
You can also import user-defined filters.
View filters in the Filters tab. Filter effects are shown graphically in the Summary tab — removed data is shown in red.
After you create them, filters can be edited in the same way as variables:
Directly, after you select-click them in a Filters tab, or by pressing F2
Using Tools > Filters, which opens the Filter Editor
By double-clicking, which also opens the Filter Editor
Delete filters by selecting them and pressing Delete.
Operating Point Filters and Operating Point Notes
If operating point groupings are defined, you can add operating point filters (to filter out entire operating points, instead of individual observations) and operating point notes (to mark every operating point that fulfills set criteria). The Operating Point Filter Editor and Operating Point Notes Editor can be reached from the Tools menu. You can view these filters in the Data Editor in the same way as the other filters by selecting Operating Point Filters or Operating Point Notes tabs. You define, edit, store, and delete these filters in the same way, and store and import them.
Note
Operating point filters are deleted when fitting one-stage models.
Filter Editor
A filter is a constraint on the data set used to exclude some records. You define the filter using logical operators on the existing variables.
For example, if you enter n>1000, the effect of
this filter is to keep all records with speed (n)
greater than 1000.
Click OK to impose new filters on the current data set.
The Filter Editor looks different depending on whether you opened it to create a new filter or edit an existing one. The example above shows the editor when adding a new filter. If you open the editor to edit a filter there is an additional list on the left. You can choose which of your existing filters to edit from this list, or click the button to add a new item to the list if you want to add a new filter.
Import Variables, Filters, and Editor Layout
You can store and import plot preferences, user-defined variables, filters, and operating point notes so that you can apply them to other data sets imported later in the session.
To store expressions in a file, in the Data Editor, select Tools > Export Expressions and select a file name.
To import, either:
Select the menu Tools > Import Expressions
Use the toolbar button
In the Import Variables, Filters, and Editor Layout dialog box, use the toolbar buttons to import variables, filters and plot layouts. Import from other data sets in the current project, or from MBC project files, or from files exported from the Data Editor.
To use imported expressions in your current project, select items in the lists and click the toolbar button to apply in the data editor.
