Chapter 2
p.38, l.-7.The sentence should read "Substituting (2.52) and (2.53) in the sandwich variance formula \(\ldots\)" (remove "the inverse of")
Chapter 7
p.289, l.-6.The first two lines of Equation (7.110) should read $$ \begin{align*} &\widehat{\mathcal{V}}_{AIPW}(d_{\eta}) = n^{-1} \sum_{i=1}^{n} \left\{ \frac{\mathcal{C}_{d_{\eta},i}Y_{i}}{\overline{\omega}_{K}(H_{Ki},A_{Ki}; \widehat{\overline{\gamma}}_{K})} \right. \\ &-\left[\frac{ \mathrm{I}\{ A_{1i}=d_{\eta,1}(H_{1i})\} - \omega_1(H_{1i},A_{1i}; \widehat{\gamma}_{1})} {\omega_1(H_{1i},A_{1i}; \widehat{\gamma}_{1})} \right] Q_{1}^{{d_{\eta}}}\{H_{1i},d_{\eta,1}(H_{1i}); \widehat{\beta}_{1}\} \end {align*} $$ (in the second term, change \(\omega_k(H_{1i},A_{1i}; \widehat{\gamma}_{1})\) to \(\omega_1(H_{1i},A_{1i}; \widehat{\gamma}_{1})\) in the numerator and denominator)
p.293, l.8.
Equation (7.122) should read $$ \begin{align*} &\mathcal{G}_{AIPW,K-1}(\underline{d}_{\eta,K-1}; \underline{\gamma}_{K-1}, \underline{\beta}_{K-1}) = \frac{\mathfrak{C}_{d_{\eta},K-1,K} Y}{\underline{\omega}_{K-1,K}(H_{K},A_{k}; \underline{\gamma}_{K-1,K}) } \\ &-\left[ \frac{ \mathrm{I}\{ A_{K-1} = d_{\eta,K-1}(H_{K-1})\} - \omega_{K-1}( H_{K-1}, A_{K-1}; \gamma_{K-1})} { \omega_{K-1}( H_{K-1}, A_{K-1}; \gamma_{K-1}) } \right] \\ &\hspace{1.1in}\times Q_{K-1}^{{d_{\eta}}}\{H_{K-1},d_{\eta,K-1}(H_{K-1}); \beta_{K-1}\} \\ &-\frac{ \mathfrak{C}_{{d_{\eta}},K-1,K-1}}{ \omega_{K-1}(H_{K-1},A_{K-1}; \gamma_{K-1}) } \!\! \left[ \frac{ \mathrm{I}\{ A_{K} = d_{\eta,K}(H_{K})\} - \omega_K( H_{K}, A_{K}; \gamma_{K})} { \omega_K( H_{K}, A_{K}; \gamma_{K}) }\right] \\ &\hspace{1.1in}\times Q_{K}^{{d_{\eta}}}\{H_{K},d_{\eta,K}(H_{K}); \beta_{K}\}, \end{align*} $$ (in the second to last line, change $$\frac{ \mathfrak{C}_{{d_{\eta}},K-1,K}}{ \underline{\omega}_{K-1,K}(H_{K},A_{K}; \underline{\gamma}_{K-1,K}) }\hspace{0.1in}\mbox{ to }\hspace{0.1in} \frac{ \mathfrak{C}_{{d_{\eta}},K-1,K-1}}{ \omega_{K-1}(H_{K-1},A_{K-1}; \underline{\gamma}_{K-1}) };$$ note that \( \mathfrak{C}_{{d_{\eta}},K-1,K-1} = \mathrm{I}\{A_{K-1} = d_{\eta,K-1}(H_{K-1})\}\))
p.303, l.-4.
The last displayed equation should read $$\widehat{\mathcal{V}}_{AIPW}(d_{\eta}) = n^{-1} \sum_{i=1}^{n} \mathcal{G}_{AIPW,1i}(d_{\eta}; \widehat{\underline{\gamma}}_1, \widehat{\underline{\beta}}_1)$$ (change \(\widehat{\underline{\gamma}}_k, \widehat{\underline{\beta}}_k\) to \(\widehat{\underline{\gamma}}_1, \widehat{\underline{\beta}}_1\))
