This financial forecasting technique looks at the relationships between two different variables in order to understand the relationship of how fluctuations in one cause changes in the other correlation modeling is probably the most widely used predictive model in finance modeling.

The workshop commissioned papers examined (1) the history and problems with models of demand and supply for scientists and engineers, (2) objectives and approaches to forecasting models, (3) margins of adjustment that have been neglected in models, especially substitution and quality, (4) the presentation of uncertainty, and (5) whether these. National weather service home page the starting point for official government weather forecasts, warnings, meteorological products for forecasting the weather, and information about meteorology. A forecast aids in determining volume of production, inventory needs, labor hours required, cash requirements, and financing needs a variety of forecasting methods are available however, consideration has to be given to cost, preparation time, accuracy, and time period. Forecasting with the model: the model must be used for short term and intermediate term forecasting this can be achieved by updating it as new data becomes available in order to minimize the number of periods ahead required of the forecast.
