Data

This section describes all aspects of loading, manipulating, and selecting data in the Model Browser. There are three main graphical interfaces for dealing with data:

• You use the Data Editor for loading, filtering, grouping, and editing data, and you can define new variables. The Data Editor contains various graphical interfaces for these tasks: the Data Import Wizard for loading and merging data; the User-Defined Variables and Filters window (with the Variable Editor, Filters Editor, and Storage dialog) for creating and storing new variables and data filters; and the Test Groupings dialog for plotting and manipulating data groups. You can reach the Data Editor from project or test plan level.
• You use the Data Wizard to select data for modeling and set up matching data to designs by setting tolerances and opening the Data Selection window. You reach the Data Wizard from test plan level.
• You use the Data Selection window 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 reach the Data Selection window from test plan level.

You can load and merge data from the following:

• From files (Excel, Concerto, MATLAB)
• From the workspace
• From tailor-made Excel sheets

See Data Loading and Merging.

Within the Data Editor, you can do the following:

• View plots, edit and add data records.
• Define new variables. See User-Defined Variables and Filtering and Variable Editor.
• Apply filters to remove unwanted records. See Filter Editor.
• Store and retrieve user-defined variables and filters. See Storage.
• Define test groupings to collect data into groups.

You use the Data Wizard to do the following:

• 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.

The Data Selection window matches data to experimental designs.
