HI everyone,
I have been a little frustrated with the fact that JMP still does not have a GAM modeling platform (even if it exists in SAS for many years) so I decided to create an add-in that is based on the mgcv package in R. So to run this add-in you will need to have R v. 3.3.3 running on your computer. It basically creates a JMP dialog window with many of the options available in the R package and retrieves the essential results from R and adds some graphs and options. If you need additional features, please let me know. Here are some screen shots of the interface and results window.
Best regards, Yves
