Errata for the 1st edition, first printing (June, 2022)

  • Page 9. At the top pf the page, “…polynomial modelpolynomial” should be “…polynomial model.” (Thanks to @RaymondBalise)

  • Page 9. Just below the figure caption, “…MSE” should be “…MSE (mean squared error).” (Thanks to @RaymondBalise)

  • Page 22. In the last paragraph, “(red curve)” should be “(black curve).” (Thanks to @RaymondBalise)

  • Page 24. Mathematical typo. At the top of the page, \(\left\{X_j\right\}_{j=1}^1 0 \stackrel{iid}{\sim} \mathcal{U}\left(0, 1\right)\) should be \(\left\{X_j\right\}_{j=1}^{10} \stackrel{iid}{\sim} \mathcal{U}\left(0, 1\right)\). (Thanks to Li Gang)

  • Page 48. Just before the function at the bottom of the page, “…image” should be “…see ?`[`.” (Thanks to @RaymondBalise)

  • Page 72. In the second to last paragraph, “…take \(\mathcal{T}_0\) to be the left tree in Figure 2.12” should be “…take T_0 to be the left tree in Figure 2.13.” (Thanks to @RaymondBalise);

  • Page 75. The phrase “…nodes \(A_5\)–\(A_7\)” is confusing (since the tree nodes are not labeled left to right and top to bottom) and should probably be changed to “…nodes \(A_9\), \(A_5\), and \(A_3\)”.

  • Page 97. “…Cleveland dot plot displayed in Figure ??” should be “…Cleveland dot plot displayed in Figure 2.24. (Thanks to @RaymondBalise)

  • Page 128. Missing closing parentheses at the end of the first paragraph in Section 3.4.4.

  • Page 197. Towards the bottom of the page, “…in an ordinary bagged tree ensemble).” should be “…in an ordinary bagged tree ensemble” (random closing parentheses).

  • Page 276. The last line of Section 7.8 uses notation that’s inconsistent with the notation in Section 6.3. In particular, “…to the difference in \(f\left(x^\star\right) - E\left[\hat{f}\left(x\right)\right] = 0.51\)” should probably be changed to “…to the difference \(\hat{f}\left(\boldsymbol{x}^\star\right) - \bar{f} = 0.51\).”

  • Page 301. In footnote “w”, sparkR should be SparkR (i.e., it’s spelled in upper camel case).
