PrefaceThis book grew out of an MBA course in analysis of financial time series that I havebeen teaching at the University of Chicago since 1999. It also covers materials ofPh.D. courses in time series analysis that I taught over the years. It is an introductorybook intended to provide a comprehensive and systematic account of financialeconometric models and their application to modeling and prediction of financialtime series data. The goals are to learn basic characteristics of financial data, understandthe application of financial econometric models, and gain experience in analyzingfinancial time series.The book will be useful as a text of time series analysis for MBA students withfinance concentration or senior undergraduate and graduate students in business, economics,mathematics, and statistics who are interested in financial econometrics. Thebook is also a useful reference for researchers and practitioners in business, finance,and insurance facing Value at Risk calculation, volatility modeling, and analysis ofserially correlated data.The distinctive features of this book include the combination of recent developmentsin financial econometrics in the econometric and statistical literature. Thedevelopments discussed include the timely topics of Value at Risk (VaR), highfrequencydata analysis, and Markov Chain Monte Carlo (MCMC) methods. In particular,the book covers some recent results that are yet to appear in academic journals;see Chapter 6 on derivative pricing using jump diffusion with closed-form formulas,Chapter 7 on Value at Risk calculation using extreme value theory based ona nonhomogeneous two-dimensional Poisson process, and Chapter 9 on multivariatevolatility models with time-varying correlations. MCMC methods are introducedbecause they are powerful and widely applicable in financial econometrics. Thesemethods will be used extensively in the future.Another distinctive feature of this book is the emphasis on real examples and dataanalysis. Real financial data are used throughout the book to demonstrate applicationsof the models and methods discussed. The analysis is carried out by using severalcomputer packages; the SCA (the Scientific Computing Associates) for buildinglinear time series models, the RATS (Regression Analysis for Time Series) forestimating volatility models, and the S-Plus for implementing neural networks andobtaining postscript plots. Some commands required to run these packages are givenxi
