Hey everyone, new to SPSS and statistics (currently enrolled in a grad course getting an introduction). We're using Andy Field's Discovering Statistics Using SPSS Statistics 5th North American edition as a text, and I'm trying to apply a robust linear regression in the Analyze --> Regression menu. His text talks about needing to have the Essentials for R plugin installed in order to see this option, and he goes through details of how to locate the right version and install it and R itself. However, I saw here that IBM says they already installed both Essentials for R plugin and R starting in version 28.0 (I am running that version - premium version), but I do not see "Robust regression" as an option in the menu.Could anyone potentially guide me as to what I might need to do in order to run that option? Hope I have been clear enough, but can supply more info if needed.Thanks!
