Dear all, currently I set up a GAM for my dataset (~32k records). I assume a normal distribution, constant variance and no correlation effects. With gam.check() it is possible to check those assumptions graphically. But is there also any option to do quantitative tests like the Wald-Test, shapiro-wilk test or VIF? Looking forward to your responses!

GAM Assumption Tests
3 messages · Collin Lynch, Mike.lang
Hi Mike, I recently had this issue and didn't find any package that implemented these tests directly for the gam object. I found it simplest just to pull the residuals from it and run tests like shapiro.test directly. Best, Collin.
