At various places in the Appendices, Chebychev should be Chebyshev. (Don Tawanpitak, University of Florida)

Appendix A, A.4.2 11/06/19

This is on page 990 in edition 7. The logic of the one line proof that AA^-1=I is circular. An easier way to get there is to rely on (B^-1)^-1=B. Then, let A=B^-1 and the result is immediate. (John Gallup, Portland State University.)

Appendix A, A.8.1 11/06/19

This is on page 1008 in edition 7. Result (A-129) is incorrect. The result should be dx'A/dx = A. It follows that dx'A'/dx = A'. Result (A-132) is correct, but it has not been established by (A-129) to (A-131). To establish (A-132) we can use the vector product rule, dg(x)'h(x)/dx = (dg(x)'/dx)h(x) + (dh(x)'/dx)g(x). Let g(x) = x, h(x) = Ax. (John Gallup, Portland State University.)

Appendix B, Equation (B-96) 6/30/17

In the quadratic form, there is a prime missing before R. This is on page 1129 in the online appendix. (Steven Wu Chaves, New York University)

184	7/30/20	Five lines below (6-5), 1.34935 should be 1.34379. Two lines below (6-6), 0.0750 should be 0.0698. (Peiming He, Chongqing University, China)
186	7/30/20	Six lines below the matrix expression, there is a ")" missing from before the superscript "1/2." (Author)
187	7/31/20	In the last line, 0.0052 should be 0.051. (Peiming He, Chongqing University, China)
194	7/31/20	In Example 6.21, 4 lines from the end,27.587 should be 209.015. (Peiming He, Chongqing University, China)

259	11/30/18	In the last row, second column of Table 8.1, 1.0301 should be 5.0261. The next two estimates of sigma should be 5.3227 and 5.1141. Note that these values all use e'e/n. At the end of the 3rd line after the first equation, u_it should be e_it. (Randy Campbell, Mississippi State University)
260	8/10/20	In the expression for rho after (8-14), subscript "w" should be "u." (Peiming He, Chongqing University, China)
261	8/10/20	In the line above Section 8.4.3, the fraction at the beginning of the line should be inverted.(Peiming He, Chongqing University, China)
407	11/30/18	In (11-33), there should be no subscript i on q_i. There is a term 1/s_e that should be added before the left square bracket. (Randy Campbell, Mississippi State University)
451	10/30/22	In the line above (11-74), "OLS" should be "GLS." In (11-87), b_i should be beta-hat_i. (Chon Van Le, International University - VNU HCMC, Vietnam)
573	4/16/20	In the sentence after the second equation, "the log of milk production," should be simply "milk production," (Mario Marshall, University of South Florida)
593	7/7/20	In lines 4 and 5, "The histogram in Figure 14.6" should state "The histogram in Figure 14.6 based on the trimmed sample of 27278 observations..." In the line after the first equation, "Figure 14.4" should say "Figure 14.6." (Emanuel Agu, CUNY Graduate Center, New York)
599	7/7/20	In Table 4.11, the constant in the Poisson results should be 1.04805. It should be noted that the standard errors for the three sets of regression results have been clustered on the observation ID. (Author and Emanuel Agu, CUNY Graduate Center, New York)
652	04/05/20	In (15-7), the standard error in the denominator should be the estimated standard error for theta^_k(b), estimated at replication k, not the standard error for the original full sample estimate as shown there. (Muhammad Asali, ISET, Tbilisi and Columbia University)
726	10/25/19	In the second line of paragraph 3, "our our" should be "our." (Stephen Devadoss, Department of Agricultural and Applied Economics, Texas Tech University)
731	10/25/19	In the line after the first equation, "in (17-3)" should be "above." (Stephen Devadoss, Department of Agricultural and Applied Economics, Texas Tech University)
735	11/6/23	After equation (17-14), "where d denotes the other variables" should be "where x_i,(d)." (Raffaele Mancuso, University of Bologna)
739	10/25/19	In the line before Example 17.4, there is a stray comma after "probability." (Stephen Devadoss, Department of Agricultural and Applied Economics, Texas Tech University)
739	7/12/18	In line 1, 10.6 should be 10.79. In line 4, 11.1 should be 11.23. (Randall Campbell, Mississippi Stata University)
748	7/12/18	In the header for Example 17.7, "Logit" should be "Probit." (Randall Campbell, Mississippi Stata University)
752,753	7/12/18	In the last line of Table 17.5 and likewise in the last line of Table 17.6, the first 0.02086 should be 0.03571. (Randall Campbell, Mississippi Stata University)
920	6/25/17	Figure 19.1 shows three truncated distributions. The rightmost one results from truncation at x = +0.5. In the rightmost label box, f(x \| x > -0.5) should be f(x \| x > +0.5) (Author)
987	11/30/18	Near the bottom of the page, r_s should be r_\|t-s\|. (Bingchen Wang, Columbia University)
990	11/30/18	Line 3. E[e_t] = 0 does not require \|r\| < 1. It is stated as an assumption. That is, (20-6) requires both (20-5) and E[e_t] = 0. (The sentence in the text is misleading as it stands. It will be correct if the "and" is moved from the end of the line to before "E[e_t] = 0.") (Bingchen Wang, Columbia University)
1035	11/30/18	In the "alternative formulation," in the middle of the page, in the first equation, in the summation, f_j should be g_j and the two expressions in the second line should be replaced with simply g* = g - 1. The same correction applies to the following equation. It should also be noted that the first ADF test is being carried out assuming that b = 0. (Bingchen Wang, Columbia University)
1096	7/13/18	In the reference to Wooldridge (1995), "Mean" should be "Mean Independence." (Alfonso Sanchez-Penalver, University of South Florida)
Appendices	11/06/19	At various places in the Appendices, Chebychev should be Chebyshev. (Don Tawanpitak, University of Florida)
Appendix A, A.4.2	11/06/19	This is on page 990 in edition 7. The logic of the one line proof that AA^-1=I is circular. An easier way to get there is to rely on (B^-1)^-1=B. Then, let A=B^-1 and the result is immediate. (John Gallup, Portland State University.)
Appendix A, A.8.1	11/06/19	This is on page 1008 in edition 7. Result (A-129) is incorrect. The result should be dx'A/dx = A. It follows that dx'A'/dx = A'. Result (A-132) is correct, but it has not been established by (A-129) to (A-131). To establish (A-132) we can use the vector product rule, dg(x)'h(x)/dx = (dg(x)'/dx)h(x) + (dh(x)'/dx)g(x). Let g(x) = x, h(x) = Ax. (John Gallup, Portland State University.)
Appendix B, Equation (B-96)	6/30/17	In the quadratic form, there is a prime missing before R. This is on page 1129 in the online appendix. (Steven Wu Chaves, New York University)
Appendix F, Tables	6/30/17	In the table entry for data set F3.1, in the description, "GNP" should be "GDP." (Alejandro Rojas, University of Texas, Rio Grande Valley)
