Someone may wonder why artificial data are used when real market data actually look quite different. The answer is, we need to understand something simple before we can understand something more complicated. This is a common venue taken by scientific research: we first create a simple model. In science, a model is a representation of a phenomenon, and can be a simplified picture of what reality actually is. To cite an example, Newton’s First Law states that an object at rest stays at rest, and an object in motion stays in motion. Force, including frictional force, is not exerted on the object. However, in real life environ- ment, forces almost always exist. In this case, a very simple model is described first, as only after we have grasped something simple should we attempt to apprehend something more complicated. Scientists constantly work on refining and improving models. An improved model can help us understand the behavior of real objects and systems
