GAM without intercept reports a huge deviance
...h a linear term and two smooth terms, all of them statistically significant but the intercept was not significant. The adjusted r2 of this model is 0.572 and the deviance 65.3. I decided to run the model again without intercept, so I used in R the following instruction: regression= gam(dependent~ +linear_independent +s(smooth_independent_1) +s(smooth_independent_2) -1,data=D) All the independent variables were significant. The adjusted r2 of this model is 0.552 and the deviance increased to 99.5! According to my knowledge, the adjusted r2 and the deviance should be more or less the same and this is the first...
