Is \"Temperature (2 degrees)\" the data from this instance, or meaning that two unit increases?\r\n2. \"contributes less towards the predicted value compared to the average\" - what is the average? Average predictions? Mean value of distribution?\r\n3. \"“days_since_2011” unusually much, because this instance is from late 2011 (5 days).\" - so the features contributes a lot because it is from late 2011 (only 5 days????). Shouldn't it be 300 days or so?\r\n\r\nThanks a lot for the book, it is very well written, but I do feel that this example needs a little bit more of step-by-step explanation.\r\ne.g.: Providing the instance, showing how it maps to the plot (calculating effects), and cross-referencing to the weight table, in order to have a full grasp of what is going on.\r\n\r\nP.S.: It would also be really nice to have the data with the extracted features in order to reproduce the work."}}
