3.8/5 | To-be-read-again, but not again and again. Arguably well carved more than a little, by a knowledgeable top notch statistician – but only a bit interesting. Berk breezes through a large number of relevant scope/validity domain’s issue: what regression (multiple linear) are good at and what they are totally not good at. I’d have been glad the author could elaborate a bit better and and in a more systematic manner on this issue, but nontheless it conjures up a pretty good case for how cautious we should be regarding the regression machinery and their assumption/hypothesis (or support), and the theoretical impedments to use them as for causal inference. Nice discussion of how these complications get usually ignored and how instrumental variable are damn good at concealing the pachyderm in the room. Not entirely sure the section dealig with Pearl's work on causal inference and DO-calculus do bring justice to this wide topic, certainly no more than a descriptive summary in any - of the few - comprehensive textbook.
