This second edition of a 1986 publication contains additions that update this book with advances in time series forecasting. New topics include the Augmented Dickey-Fuller test, the model identification methods ESACF, SCAN and MINIC, unequal variances in time series models, and cointegration. The revisions and reorganization to chapter seven, Spectral Analysis, improve readability and comprehension. The addition of the final chapter, 'Data Mining and Forecasting', provides an introduction to the menu driven Time Series Forecasting System. SAS users who model and forecast time series data should add this book to their collection, including owners of the first edition. --Barry A. Evans, Ph.D., Manager, Forecasting GlaxoSmithKline

Preface
A time series is a set of ordered observations on a quantitative characteristic of a phenomenon at equally spaced time points. The goal of univariate time series analysis is to forecast values of a single historical series. The goal of multivariate time series analysis can be to model the relationships among component series as well as to forecast those components.

Time series analysis can be accomplished most effectively by the SAS procedures ARIMA, STATESPACE, SPECTRA, and VARMAX. To use these procedures properly, you must (1) understand the statistics you need for the analysis and (2) know how to invoke the procedures. SAS for Forecasting Time Series, Second Edition, makes it easier for you to apply these procedures to your data analysis problems.

Chapter 1, Overview of Time Series, reviews the goals and key characteristics of time series. The analysis methods available through SAS/ETS software are presented, beginning with the simpler procedures FORECAST, AUTOREG, and X11 and continuing with the more powerful SPECTRA, ARIMA, and STATESPACE. This chapter shows the interrelationships among the various procedures. It ends with a discussion of linear regression, seasonality in regression, and regression with transformed data.

Chapter 2, Simple Models: Autoregression, presents the statistical background necessary to model and forecast simple autoregressive (AR) processes. A three-part forecasting strategy is used with PROC ARIMA to identify, estimate, and forecast. The backshift notation is used to write a time series as a weighted sum of past shocks and to compute covariances through the Yule-Walker equations. The chapter ends with an example involving an AR process with regression techniques by overfitting.

Chapter 3, The General ARIMA Model, extends the class of models to include moving averages and mixed ARMA models. Each model is introduced with its autocovariance function. Estimated autocovariances are used to determine a model to be fit, after which PROC ARIMA is used to fit the model, forecast future values, and provide forecast intervals. A section on time series identification defines the autocorrelation function, partial autocorrelation function, and inverse autocorrelation function. Newer identification techniques are also discussed. A catalog of examples is developed, and properties useful for associating different forms of these functions with the corresponding time series are described. This chapter includes the results of 150 observations generated from each of eight sample series. Stationarity and invertibility, nonstationarity, and differencing are discussed.

Chapter 4, The ARIMA Model: Introductory Applications, describes the ARIMA model and its introductory applications. Seasonal modeling and model identification are explained, with Box and Jenkins’s popular airline data modeled. The chapter combines regression with time series errors to provide a richer class of forecasting models. Three cases are highlighted: Case 1 is a typical regression, case 2 is a simple transfer function, and case 3 is a general transfer function.
New in Chapter 4 for the second edition are several interesting intervention examples involving analyses of :
1. the effect on calls of charging for directory assistance
2. the effect on milk purchases of publicity about tainted milk
3. the effect on airline stock volume of the September 11, 2001, terrorist attacks.

Chapter 5, The ARIMA Model: Special Applications, extends the regression with time series errors class of models to cases where the error variance can change over time—the ARCH and GARCH class. Multivariate models in which individual nonstationary series vary together over time are referred to as “cointegration” or “error correction” models. These are also discussed and illustrated.
This chapter presents new developments since the first edition of the book.

Chapter 6, State Space Modeling, uses the AR model to motivate the construction of the state vector. Next, the equivalence of state space and vector ARMA models is discussed. Examples of multivariate processes and their state space equations are shown. The STATESPACE procedure is outlined, and a section on canonical correlation analysis and Akaike’s information criterion is included. The chapter ends with the analysis of a bivariate series exhibiting feedback, a characteristic that cannot be handled with the general ARIMA transfer function approach.

When we think of great leaders, it's usually the charismatic, globally influential Churchill, Patton, Jack Welch who spring to mind. But as Harvard Business School professor Badaracco (Defining Moments: When Managers Must Choose Between Right and Right) correctly points out, everyday leadership is not so dramatic, and daily leadership decisions are rarely carried out at the top of an organization. Badaracco focuses here is on helping the middle- and senior-level managers who make the ordinary decisions that ultimately determine an organization's success. As he puts it: "What usually matters are careful, thoughtful, small, practical efforts by people working far from the limelight. In short, quiet leadership is what moves and changes the world." Out of a four-year study of these real-life leaders, Badaracco describes eight strategies for making effective leadership decisions in murky situations where the "right" thing is far from obvious. The strategies range from the commonsensical (truly examine the question at hand; don't ignore corporate politics) to the counterintuitive (don't expect to be wholly altruistic and accept that some of your motives are self-interested; try not to make important decisions as quickly as possible). Badaracco presents each principle with a brief introduction, followed by a case study and summary of the lessons to be learned. The sum is a useful checklist middle-level managers can put to work immediately.

Foresight can be crucial in process and production control, production-and-resources planning and in management decision making generally. Although forecasting the future from accumulated historical data has become a standard and reliable method in production and financial engineering, as well as in business and management, the use of time series analysis in the on-line milieu of most industrial plants has been more problematic because of the time and computational effort required.

The advent of intelligent computational technologies such as the neural network and the genetic algorithm promotes the efficient solution of on-line forecasting problems. Their most outstanding successes include:

prediction of nonlinear time series and the nonlinear combination of forecasts using neural networks;
prediction of chaotic time series and of output data for second-order nonlinear plant using fuzzy logic.
The power of intelligent technologies applied individually and in combination, has created advanced forecasting methodologies, exemplified in Computational Intellingence in Time Series Forecasting by particular systems and processes. The authors give a comprehensive exposition of the improvements on offer in quality, model building and predictive control, and the selection of appropriate tools from the plethora available using such examples as:

forecasting of electrical load and of output data for nonlinear plant with neuro-fuzzy networks;
temperature prediction and correction in pyrometer reading, tool-wear monitoring and materials property prediction using hybrid intelligent technologies;
evolutionary training of neuro-fuzzy networks by the use of genetic algorithms and prediction of chaotic time series;
isolated use of neural networks and fuzzy logic in the nonlinear combination of traditional forecasts of temperature series obtained from a pilot-scale chemical reactor with temporarily disconnected controller.
Application-oriented engineers in process control, manufacturing, the production industries and research centres will find much to interest them in Computational Intelligence in Time Series Forecasting and the book is suitable for industrial training purposes. It will also serve as valuable reference material for experimental researchers.

In modern financial practice, asset prices are modelled by means of stochastic processes, and continuous-time stochastic calculus thus plays a central role in financial modelling. This approach has its roots in the foundational work of the Nobel laureates Black, Scholes and Merton. Asset prices are further assumed to be rationalizable, that is, determined by equality of demand and supply on some market. This approach has its roots in the foundational work on General Equilibrium of the Nobel laureates Arrow and Debreu and in the work of McKenzie. This book has four parts. The first brings together a number of results from discrete-time models. The second develops stochastic continuous-time models for the valuation of financial assets (the Black-Scholes formula and its extensions), for optimal portfolio and consumption choice, and for obtaining the yield curve and pricing interest rate products. The third part recalls some concepts and results of general equilibrium theory, and applies this in financial markets. The last part is more advanced and tackles market incompleteness and the valuation of exotic options in a complete market.

A Practical Guide to Forecasting Financial Market Volatility
Wiley; 1 edition (June 17, 2005)
ISBN: 0470856130
236 pages PDF 1,1 Mb

Financial market volatility forecasting is one of today's most important areas of expertise for professionals and academics in investment, option pricing, and financial market regulation. While many books address financial market modelling, no single book is devoted primarily to the exploration of volatility forecasting and the practical use of forecasting models. A Practical Guide to Forecasting Financial Market Volatility provides practical guidance on this vital topic through an in-depth examination of a range of popular forecasting models. Details are provided on proven techniques for building volatility models, with guide-lines for actually using them in forecasting applications.

"Professor Poon exposes in her book current state-of-the-art volatility forecasting methods. Beginning with a description of various conditional volatility models, be it discrete or continuous, the link with option pricing models is well established. The book proceeds with surveying the current volatility literature: what type of volatility should be used to price options, how can volatility of various assets be predicted, how volatility can be used within a value-at-risk setting. This well written book should be useful both for the practitioner and the academic/student interested in volatility."

Macroeconometric models, in many ways the flagships of the economist's profession in the 1960s, came under increasing attack from both theoretical economist and practitioners in the late 1970s. Critics referred to their lack of microeconomic theoretical foundations, ad hoc models of expectations, lack of identification, neglect of dynamics and non-stationarity, and poor forecasting properties. By the start of the 1990s, the status of macroeconometric models had declined markedly, and had fallen completely out of, and with, academic economics. Nevertheless, unlike the dinosaurs to which they often have been likened, macroeconometric models have never completely disappeared from the scene. This book describes how and why the discipline of macroeconometric modelling continues to play a role for economic policymaking by adapting to changing demands, in response, for instance, to new policy regimes like inflation targeting. Model builders have adopted new insights from economic theory and taken advantage of the methodological and conceptual advances within time series econometrics over the last twenty years. The modelling of wages and prices takes a central part in the book as the authors interpret and evaluate the last forty years of international research experience in the light of the Norwegian 'main course' model of inflation in a small open economy. The preferred model is a dynamic model of incomplete competition, which is evaluated against alternatives as diverse as the Phillips curve, Nickell-Layard wage curves, the New Keynesian Phillips curve, and monetary inflation models on data from the Euro area, the UK, and Norway. The wage price core model is built into a small econometric model for Norway to analyse the transmission mechanism and to evaluate monetary policy rules. The final chapter explores the main sources of forecast failure likely to occur in a practical modelling situation, using the large-scale nodel RIMINI and the inflation models of earlier chapters as case studies
