Workspace Node: Predictor Screening - Specifications - Quick Tab

The Predictor Screening workspace node can be accessed from the Feature Finder, the ribbon bar, or the Node Browser. The Specifications - Quick tab is displayed by default when the specifications dialog box is opened.

Element Name Description
Use previous input description Select this check box to use the variable selection specified in the Select dependent variables and predictors node, accessed via the ribbon bar or by double-clicking the data source node in the workspace. Note that the previous Select Cases and Weight specifications will be used also. If case selection conditions and/or weights were previously specified, you can view those specifications from this workspace dialog box, but you cannot change them (the options will be dimmed).
Variables Click this button to display a variable selection dialog box. You can select continuous, categorical, and binary dependent variables, and continuous and categorical predictors. Continuous variables are those that are measured on some continuous scale (e.g., Height, Weight), categorical variables contain indicators, codes, or text values to denote membership in some group or class (e.g., Gender: Male, Female). A binary variable is a categorical variable that can take on only two values. Statistica refers to these two values as good and bad. The code associated with the bad code is the event of interest, e.g., in a credit scoring application, the bad code might denote those customers that have defaulted on a loan.
Response codes This button is available only after a categorical dependent variable has been specified. Click the Response codes button to display the Select Response Codes dialog box, in which you make a selection for the Categorical response from the list of codes for the Dependent variable selected in the current analysis. The list of codes can be displayed by clicking the Zoom button. Note that you must select at least two codes for the selected Dependent variable.
Bad code If a binary dependent variable has been specified, a bad code (event of interest) must also be specified.
Good code If a binary dependent variable has been specified, a good code (non-event) must also be specified.
Factor codes Once you have selected one or more categorical predictor variables, the button for the selection of the factor codes will be available. Click the Factor codes button to display the Select Factor Codes dialog box, in which you select codes for the Categorical predictors. The list of codes can be displayed by clicking the Zoom button. Note that you must select at least two codes for each of the selected Categorical predictors.

Options / C. See Common Options.

OK Click the OK button to accept all the specifications made in the dialog box and to close it. The analysis results will be placed in the Reporting Documents node after running (updating) the project.
