El Analisis de la Realidad Social Modelos Estructurales de Covarianzas

PDF | español | 7Mb

La metodología y las técnicas de investigación implican, simultáneamente, diferentes objetos de reflexión. Podemos distinguir, a grandes rasgos, tres referentes distintos que son objeto interés. En primer lugar, encontramos la reflexión centrada sobre las características que posee la realidad y que le hace cognoscible desde una determinada perspectiva cultural implica, por lo tanto, que pueda ser la realidad y en que medida es factible elaborar sobre ella un tipo concreto de conocimientos.

Econometric Analysis + Solved

PDF | english | 7Mb

Econometric Analysis is intended for a one-year graduate course in econometrics for social scientists. The prerequisites for this course should include calculus, mathematical statistics, and an introduction to econometrics at the level of, say, Gujarati’s Basic Econometrics(McGraw-Hill, 1995) or Wooldridge’s Introductory Econometrics: A Modern Approach [South-Western (2000)]. Self-contained (for our purposes) summaries of the matrix algebra, mathematical statistics, and statistical theory used later in the book are given in Appendices A through D. Appendix E contains a description of numerical methods that will be useful to practicing econometricians. The formal presentation of econometrics begins with discussion of a fundamental pillar, the linear multiple regression model, in Chapters 2 through 8. Chapters 9 through 15 present familiar extensions of the single linear equation model, including nonlinear regression, panel data models, the generalized regression model, and systems of equations. The linear model is usually not the sole technique used in most of the contemporary literature. In view of this, the (expanding) second half of this book is devoted to topics that will extend the linear regression model in many directions. Chapters 16 through 18 present the techniques and underlying theory of estimation in econometrics, including GMM and máximum likelihood estimation methods and simulation based techniques.We end in the last four chapters, 19 through 22, with discussions of current topics in applied econometrics, including time-series analysis and the analysis of discrete choice and limited dependent variable models.

Chapter 1 discusses the scope of econometrics and raises general issues that result from the application of econometric methods. Section 1.3 examines the kinds of data sets that are used in business, economics, and other social sciences. Section 1.4 provides an intuitive discussion of the difficulties associated with the inference of causality in the social sciences.
