In prior decades, most financial statistical copulations regarding quantity or performance over time series exhibited a considerable focus upon the starting point. What is the magnitude or prevailing conditions at the beginning of an observed series which will be subject to later change, in the case of finance that change is most likely to be financial market volatility, or stock performance. (Bandorff-Nielsen & Shepard, 2002) In order to measure the outcome of a particular data set (such as the performance of the economy of the United Kingdom) focus was given to the starting point alone.Over the years, as market conditions grew more complex, increasing demand was perceived for the estimation and calculation of risk and uncertainty for macro-economic theory in general. In order to devise a more comprehensive predictive tool for fluctuations in performance factors with a strong temporal variant component a new form of structural dynamic econometric calculations were envisioned. The first Autoregressive Conditional Heteroskedasticity ARCH modeling techniques were devised in the early 1980s (Engle, 1982).With this sort of modeling, the principal consideration is volatility. (Schwert, 1990) But in order to answer the question of temporal fluctuations of a given quantity over time it is not enough to simply plug in a single function describing change over time. Arch modeling concerns itself with time varying volatility of insight is required to quantify these changes in volatility over time....

(Schwert, 1990) But in order to answer the question of temporal fluctuations of a given quantity over time it is not enough to simply plug in a single function describing change over time. Arch modeling concerns itself with time varying volatility; changes in the rate of change or potential change. These systems may be characterized by a progression in which there is a rapid series of shifts or fluctuations which punctuate placid periods of slower change. It is not incomprehensible to identify the rate of change for any phenomena and, but a higher order of insight is required to quantify these changes in volatility over time. After the initial process has begun, arch modeling allows calculations of the second order moments. More
