Working with Data in the Model Browser
This section describes all aspects of importing, manipulating, and selecting data in the Model Browser. The Data Editor provides a powerful graphical interface for dealing with data:
Plot, filter, group, and edit data, and you can define new variables. You can match data to designs. You can reach the Data Editor from every node in the model tree, so you can also examine and export your modeling data. The Data Editor contains various tools for these tasks:
Data Import Wizard for importing and merging data
Variable Editor, Filter Editor, Operating Point Filter Editor, and Operating Point Notes Editor are dialog boxes for creating and editing new variables and data filters.
Storage dialog box for storing new variables, data filters, and plot settings
Operating Point Groupings dialog box can be used for plotting and manipulating data groups.
Within the Data Editor there are 2-D, 3-D, and multiple data plots for viewing data, and design match plots for viewing data and design points.
You use the Data Editor for matching data to experimental designs. You can set tolerances for automatic selection of the nearest data points to the specified design points, or select data points manually.
You use the Data Wizard to select data for modeling. You can also set up matching data to designs by setting tolerances and automatically opening the Design Match views within the Data Editor. You reach the Data Wizard from test plan level.
You can import and merge data from the following:
From files (Excel®, Concerto®, MATLAB®)
From the workspace
You can also write your own data-importing functions.
In the Data Editor, you can do the following:
View plots, edit and add data records.
Define new variables.
Apply filters to remove unwanted records, filter by operating point, and apply notes to operating points that fulfill set criteria.
Store and retrieve user-defined variables and filters.
Collect data into groups.
Match data to experimental designs using the Design Match views.
Export data and modeling output to file and to the workspace.
Use the Data Wizard to:
Select the data set and design to use for modeling.
Select the data signals to use for model input factors (one-stage, or local and global for two-stage).
Select matching tolerances (if matching data to a design).
Select data signals for response model input factors.
