Building Models Quick Start

• Once data has been loaded into the workspace, there are several ways to begin building a model. For analysis tools like PCA where only an X block is required, you can right-click on the data icon in the Browser to reveal a list of analysis options. You can also drag the given data to an analysis method shortcut, such as the Decompose PCA shortcut.

• The Analysis GUI will then appear with the given data already loaded. (The large X (block) button in the Analysis GUI will appear depressed indicating the data is loaded - passing the cursor over the button will provide a summary of the X block data.)

• While each analysis type has its own nuances, in general the steps to build a model are
  • load the data
  • view the data
  • choose preprocessing
  • select the type of cross-validation to use (if any is desired - see Using Cross-Validation)
  • build the model
  • review the model

• There is more than one way to accomplish each of the above steps. For example, preprocessing can be set for the X block by
  • clicking the "Choose Preprocessing" button in the Analysis Flowchart
  • clicking the P button next to the X button
  • select "Preprocess" menu item

(Hint: Once selected, use the Preprocess/X-block and Preprocess/Y-block menus to save the current preprocessing as the default.)

• You can quickly view your data by right-clicking on the appropriate button (X or Y) and then select "Plot Data"

• Perhaps the quickest way for new users to complete the remaining steps to build the model is to use the flowchart.
