Introduction

Human being has always been in a dire need for predicting the future events because his past experiences have assured them that early detection of the future could provide him with a better opportunity to get ready for these future events. Therefore, we find that societies in the past were replete with those who were doing chiromancy (palm reading) and clairvoyance, and other methods that are deemed today devoid of scientific basis, however, they were only enough to satisfy an important need of the human needs to foretell the future, and roll up the sleeve for it. However, with the progress and development of human experience and their use of the advanced quantitative methods, prediction has become a more effectively scientific and accurate tool to predict the future events, which has served to boost the readiness of individuals and companies in a response to the potential changes in the different fields, including the market changes and size and pattern of demand for products.
