It estimates the rate of growth and potential demand for the new product as the basis of some growth pattern of an established product. In input-output accounting two matrices used are the transaction matrix and the input co-efficient matrix.

Thus only the secular trend is left. Seasonal fluctuations follow a consistent pattern each year so the period is always known.

If you select a cell in one of your series, Excel automatically selects the rest of the data. It helps in saving the wastages in material, man hours, machine time and capacity. These individual forecasts are discussed and agreed with the sales manager.

The act of making a forecast is the expression of an opinion. The same rule applies to forecasting.

This is often a valid assumption when forecasting short term horizons, but it falls short when creating medium and long term forecasts. Trend extrapolation - These methods examine trends and cycles in historical data, and then use mathematical techniques to extrapolate to the future.

Second, the usefulness of a forecast does not always seem to be related to its accuracy. The extraordinary complexity of social systems makes it difficult to include all the relevant factors in any model. When he states that something is impossible, he is very probably wrong.Multiple regression analysis is the most common technique.

Unlike trend extrapolation models, which only look at the history of the variable being forecast, multiple regression models look at the relationship between the variable being forecast and two or more other variables.
