11 Chapter Linear regression Example Old Faithful Geyser in Yellowstone National Park, Wyoming, derives its name and its considerable fame from regularity (and beauty) of its eruptions. As they do with most geysers in the park, rangers post the predicted times of eruptions on signs nearby, and people gather beforehand to witness the show. R.A. Hutchinson, a park geologist, collected measurements of the eruption durations (X, in minutes) and the subsequent intervals before next eruption (Y , in minutes) over an 8 day period. This data is as follows 4 75 4 1 78 4.4 2 80 4.3 3 76 4.5 4 73 3.7 1 74 3.9 2 56 1.7 3 82 3.9 4 67 3.7 1 68 4 2 80 3.9 3 84 4.3 4 68 4.3 1 76 4 2 69 3.7 3 53 2.3 4 86 3.6 1 80 3.5 2 57 3.1 3 86 3.8 4 72 3.8 2 90 4 3 51 1.9 1 84 4.1 4 75 3.8 1 50 2.3 2 42 1.8 3 85 4.6 4 75 3.8 1 93 4.7 2 91 4.1 3 45 1.8 4 66 2.5 1 55 1.7 2 51 1.8 3 88 4.7 4 84 4.5 1 76 4.9 2 79 3.2 3 51 1.8 4 70 4.1 3 80 4.6 1 58 1.7 2 53 1.9 4 79 3.7 1 74 4.6 2 82 4.6 3 49 1.9 4 60 3.8 1 75 3.4 2 51 2 3 82 3.5 4 86 3.4 5 5 5 5 5 5 5 5 5 5 5 5 5 5 71 67 81 76 83 76 55 73 56 83 57 71 72 77 4 2.3 4.4 4.1 4.3 3.3 2 4.3 2.9 4.6 1.9 3.6 3.7 3.7 6 6 6 6 6 6 6 6 6 6 6 6 6 6 55 75 73 70 83 50 95 51 82 54 83 51 80 78 1.8 4.6 3.5 4 3.7 1.7 4.6 1.7 4 1.8 4.4 1.9 4.6 2.9 7 7 7 7 7 7 7 7 7 7 7 7 7 81 53 89 44 78 61 73 75 73 76 55 86 48 3.5 2 4.3 1.8 4.1 1.8 4.7 4.2 3.9 4.3 1.8 4.5 2 8 8 8 8 8 8 8 8 8 8 8 8 8 77 73 70 88 75 83 61 78 61 81 51 80 79 4.2 4.4 4.1 4.1 4 4.1 2.7 4.6 1.9 4.5 2 4.8 4.1 1.
