Abstract: Problem statement: Forecasting is a function in management to assist decision making. It is also described as the process of estimation in unknown future situations. In a more general term it is commonly known as prediction which refers to estimation of time series or longitudinal type data. Gold is a precious yellow commodity once used as money. It was made illegal in USA 41 years ago, but is now once again accepted as a potential currency. The demand for this commodity is on the rise. Approach: Objective of this study was to develop a forecasting model for predicting gold prices based on economic factors such as inflation, currency price movements and others. Following the melt-down of US dollars, investors are putting their money into gold because gold plays an important role as a stabilizing influence for investment portfolios. Due to the increase in demand for gold in Malaysian and other parts of the world, it is necessary to develop a model that reflects the structure and pattern of gold market and forecast movement of gold price. The most appropriate approach to the understanding of gold prices is the Multiple Linear Regression (MLR) model. MLR is a study on the relationship between a single dependent variable and one or more independent variables, as this case with gold price as the single dependent variable. The fitted model of MLR will be used to predict the future gold prices. A naive model known as “forecast-1” was considered to be a benchmark model in order to evaluate the performance of the model. Results: Many factors determine the price of gold and based on “a hunch of...

Forecasting

...FORECASTING - a method for translating past experience into estimates of the future. Forecasting is the process of making statements about events whose actual outcomes (typically) have not yet been observed. A commonplace example might be estimation of the expected value for some variable of interest at some specified future date. Prediction is a similar, but more general term. Both might refer to formal statistical methods employing time series, cross-sectional or longitudinal data, or alternatively to less formal judgemental methods. Usage can differ between areas of application: for example in hydrology, the terms "forecast" and "forecasting" are sometimes reserved for estimates of values at certain specific future times, while the term "prediction" is used for more general estimates, such as the number of times floods will occur over a long period. Risk and uncertainty are central to forecasting and prediction; it is generally considered good practice to indicate the degree of uncertainty attaching to forecasts. The process of climate change and increasing energy prices has led to the usage of Egain Forecasting of buildings. The method uses Forecasting to reduce the energy needed to heat the building, thus reducing the emission of greenhouse gases. Forecasting is used in the practice of Customer Demand Planning in every day business forecasting for manufacturing companies.

Research on Gold Price

...International Journal of Applied Business and Economic Research, Vol. 9, No. 2, (2011): 145-165 STUDY ON DYNAMIC RELATIONSHIP AMONG GOLD PRICE, OIL PRICE, EXCHANGE RATE AND STOCK MARKET RETURNS K. S. Sujit1 and B. Rajesh Kumar2 Abstract: The dynamic and complex relationship among economic variables has attracted the researchers, policy makers and business people alike. This study is an attempt to test the dynamic relationship among gold price, stock returns, exchange rate and oil price. All these variables have witnessed significant changes over time and hence, it is absolutely necessary to validate the relationship periodically. This study takes daily data from 2nd January 1998 to 5th June 2011, constituting 3485 observations. Using techniques of time series the study tried to capture dynamic and stable relationship among these variables using vector autoregressive and cointegration technique. The results show that exchange rate is highly affected by changes in other variables. However, stock market has fewer roles in affecting the exchange rate. In this study we tested two models and one model suggests that there is weak long term relationship among variables. JEL classification: C22; E3; Keywords: Unit root tests; granger causality test, Cointegration; Vector auto regression (VAR) INTRODUCTION Gold was one of the first metals humans excavated. Gold as an asset has a hybrid nature: it is a commodity used in many industries but also it has maintained throughout......

Using Neural Networks to Forecast Stock Markets

...Using Neural Networks to Forecast Stock Market Prices Abstract This paper is a survey on the application of neural networks in forecasting stock market prices. With their ability to discover patterns in nonlinear and chaotic systems, neural networks offer the ability to predict market directions more accurately than current techniques. Common market analysis techniques such as technical analysis, fundamental analysis, and regression are discussed and compared with neural network performance. Also, the Efficient Market Hypothesis (EMH) is presented and contrasted with chaos theory and neural networks. This paper refutes the EMH based on previous neural network work. Finally, future directions for applying neural networks to the financial markets are discussed. 1 Introduction From the beginning of time it has been man’s common goal to make his life easier. The prevailing notion in society is that wealth brings comfort and luxury, so it is not surprising that there has been so much work done on ways to predict the markets. Various technical, fundamental, and statistical indicators have been proposed and used with varying results. However, no one technique or combination of techniques has been successful enough to consistently "beat the market". With the development of neural networks, researchers and investors are hoping that the market mysteries can be unraveled. This paper is a survey of current market forecasting techniques with an emphasis on why they are......

Forecasting of Commodity Prices

...Forecasting and Analyzing World Commodity Prices René Lalonde* Principal Researcher International Department Bank of Canada Zhenhua Zhu Economist Research Department Bank of Canada October 18, 2002 Frédérick Demers** Economist Research Department Bank of Canada Abstract This paper develops simple econometric models to analyze and forecast three components of the Bank of Canada commodity price index (BCPI), namely non-energy commodity prices (BCNE), the West Texas Intermediate crude oil price (WTI), and other energy prices. In the paper, we present different methodologies to identify transitory and permanent components of movements in these prices. A structural vector autoregressive (SVAR) model is used for real BCNE prices, a multiple structural-break technique is employed for real crude oil prices, and an errorcorrection model is constructed for real prices of other energy components. Then we use these transitory and permanent components to develop forecasting models. We assess our models’ performance in various aspects, and our main results indicate: (a) for real BCNE prices, most of the short-run variation is attributed to demand shocks, (b) the world economic activity and real U.S. dollar effective exchange rate explain much of the cyclical variation of real BCNE prices, (c) real crude oil prices have two structural breaks over the sample period, and their link with the world economic activity is strongest in the most recent regime, (d) real prices of other energy......

...languages. But widespread availability of statistical package software has changed the reality to some extent. Now more emphasis is given on the application of the techniques to solve the business problems. So there is a need to understand the meaning of the statistical procedures. This book has been written to cater that need. In this book, all the necessary concepts have been explained keeping the business problem in mind. Also, to remove the apathy for statistics, use of mathematical expressions have been limited. That doesn‘t imply that we don‘t have to study the mathematics part. The intention is to put the substance over matter. As the students get accustomed to these statistical concepts, they can go for further investigations using various mathematical and statistical techniques. A list of suggested books and links have been given in the appendix. This book is directly related to the instructor‘s presentation. So it is highly advised that students should go through this material at the end of each class. As for general reading, the reader is advised to go according to the chapters. Chapters have been arranged in the order of higher complexity. So the initial chapters are very important. In this book, the statistical procedures have been implemented on SAS. The explanations of the codes have been from the perspective of a data modeler. For the perspective of a programmer, the students are advised to go...
