Bayesian methods are increasingly becoming attractive to researchers in many fields. Econometrics, however, is a field in which Bayesian methods have had relatively less influence. A key reason for this absence is the lack of a suitable advanced undergraduate or graduate level textbook. Existing Bayesian books are either out-dated, and hence do not cover the computational advances that have revolutionized the field of Bayesian econometrics since the late 1980s, or do not provide the broad coverage necessary for the student interested in empirical work applying Bayesian methods. For instance, Arnold Zellner’s seminal Bayesian econometrics book (Zellner, 1971) was published in 1971. Dale Poirier’s influential book (Poirier, 1995) focuses on the methodology and statistical theory underlying Bayesian and frequentist methods, but does not discuss models used by applied economists beyond regression. Other important Bayesian books, such as Bauwens, Lubrano and Richard (1999), deal only with particular areas of econometrics (e.g. time series models). In writing this book, my aim has been to fill the gap in the existing set of Bayesian textbooks, and create a Bayesian counterpart to the many popular non-Bayesian econometric textbooks now available (e.g. Greene, 1995). That is, my aim has been to write a book that covers a wide range of models and prepares the student to undertake applied work using Bayesian methods. This book is intended to be accessible to students with no prior training in econometrics, and only a single course in mathematics (e.g. basic calculus). Students will find a previous undergraduate course in probability and statistics useful; however Appendix B offers a brief introduction to these topics for those without the prerequisite background. Throughout the book, I have tried to keep the level of mathematical sophistication reasonably low. In contrast to other Bayesian and comparable frequentist textbooks, I have included more computer-related material. Modern Bayesian econometrics relies heavily on the computer, and developing some basic programming skills is essential for the applied Bayesian. The required level of computer programming skills is not that high, but I expect that this aspect of Bayesian econometrics might be most unfamiliar to the student brought up in the world of spreadsheets and click-and-press computer packages. Accordingly, in addition to discussing computation in detail in the book itself, the website associated with the book contains MATLAB programs for performing Bayesian analysis in a wide variety of models. In general, the focus of the book is on application rather than theory. Hence, I expect that the applied economist interested in using Bayesian methods will find it more useful than the theoretical econometrician.

MATLAB用拟合出的代码绘图高频计量经济学: HAR与神经网络 (免责声明:高频计量经济学,高频数据处理,HAR,神经网络,袋装,交叉验证,贝叶斯合奏) 受Hillebrand&Medeiros(2009)和Corsi(2009)的启发,我将神经网络置于高频环境中,并测试了两种模型(HAR&Neural Networks)的性能。 -该项目中使用的数据是标准普尔500股股票2年内日内5分钟的实际波动价值(请参阅:Sheppard,Patton,Liu,2012年),已使用双变量分析和操作方法对其进行了仔细检查。 模型简介: HAR(异构自回归模型): 该模型由Corsi在2009年开发,它基于一个简单的回归框架。 自变量分别是每日波动率分别滞后1、5和22天。 这是为了模拟昨天,一周前和大约一个月前的波动(仅考虑公开市场交易日)。 这种类型的模型也称为“长记忆”模型,因为它可以“记住” 22个市场日之前发生的情况。 它如何直观地发挥作用?:由于交易频率较高的交易者将其策略基于过去的长期波动性来预测未来,并相应地更改其策略,因此会造成短期波动性。 这种行为对交易频率较低的交易者没有影响
