Book Econometric Analysis of Cross Section and Panel Data By Wooldridge - Chapter 19 pptx

... Poisson. In Section 19. 3 we discuss other count data models, and in Section 19. 4 we cover quasi-MLEs for other nonnegative response variables. In Section 19. 5 we cover mul- tiplicative panel data models, ... some of which we cover in Sections 19. 3 and 19. 4. Wooldridge (199 7c) gives an example of Poisson regression to an economic model of crime, where the res...

See, for example, Quah (199 4), Pesaran and Smith (199 5), Kao (199 9), and Phillips and Moon (199 9). 1.2.2 Asymptotic Analysis Throughout this book we focus on asymptotic properties, ... cross section analysis the asymptotics is as the number of observations, denoted N throughout this book, tends to infinity. Usually what is meant by this statement is obvio...

... e¤ect of w on Eðy jw; cÞ, holding c fixed, is easily estimated. Unfortunately, complications often arise in the collection and analysis of economic data because of the nonexperimental nature of economics. ... positions of x and w have been switched on the right-hand side of equation (2.20) compared with equation (2 .19) . The result in equation (2.20) follows easily from th...

... square root of the appropriate diagonal ele- ment of ^ VV N =N. The asymptotic standard errors can be loosely thought of as estimating the standard deviations of the elements of ^ yy N , and they ... Limiting Behavior of Estimators and Test Statistics In this section, we apply the previous concepts to sequences of estimators. Because estimators depend on the random outcomes...

In Chapter 4 we review the single-equation linear ... for cross section data as well as begin our analysis of panel data. Chapter 8 builds on the framework from Chapter 7 but considers the case where some expl...
