How does the modeling nodes handle missing values if you don't do anything to missing values when preparing the data?

Hi, SPSSers,

 

If one doesn’t clean the data for missing values, how do the modeling nodes handle records with missing values if the modeling node’s settings don’t have a corresponding option for you to specify?

 

Thanks!

Most procedures have a MISSING subcommand or the equivalent, but the missing choices are sometimes not included in the dialog boxes, so you would need to paste and edit the syntax if working through the UI.  GLM is an example of this.  The Command Syntax Reference provides details.  Otherwise, consult the Algorithms documentation for the procedure of interest.
