normally distributed is relaxed by allowing it to follow any distribution from the exponential family(for example(normal)Poisson,binomial,gamma etc.). Inference for GLMs is based on likelihood theory, as is explained,quite fully, in chapter 2,where the practical use of these models is also ...

GAM models with five smooth functions provided a close fit to the data with 78% of the deviance explained for measured OH and 83% for modelled OH. The GAM model for measured OH produced substantially better predictions of OH concentrations than the original MCM model results. The diurnal ...
Updated residual = current residual – (learning rate)·(response explained by new tree) If adding the set of trees improves the model fit (that is, reduces the deviance of the fit by a value larger than the tolerance), then fitrgam moves to the next iteration. If adding the set of tr...
