Dear SPSS Community,
I really really need your help. I would be so greatful if there is a simple solution.
So I am currently working on my doctoral dissertation and unfortunately encountering some difficulties with SPSS (version 29, university license).
On the recommendation of my statistician, I would like to run a Lasso regression.
I have already downloaded and checked the extension. However, I can only access the options field (see screenshot) and I am never able to select variables. I have tried reinstalling the extension, and I also installed and uninstalled SPSS on several different university computers but the problem persists. If I write a syntax, SPSS tells me theres an error and it doesn’t know the method “LASSO”. As a result, I am unable to run the Lasso regression.
I have also contacted our internal IT support, but unfortunately we were not able to find a solution.
In addition, I would like to perform a Tobit regression. Unfortunately, I cannot find this option at all in our version of SPSS.
Since I am working under a very tight deadline, I would be extremely grateful for your advice and support.
Thank you very much in advance for your help.
Best regards,
Lisa-Marie Amler
