The process of judgement in determining the quantity of the product that will be demanded in the market place at a given time is known as demand prediction. This is important not only in preventing losses due to the inventory accumulation that results from over-production, also as part of a social obligation of a corporation that has to aid in stablizing the market by appropriately meeting the demand.
Such a demand prediction can be calculated using Method of least squares. the foundation of regression analysis, a statistical method of analyzing the relationship between two or more variables. It predicts how other variables react as the one variable changes. The relationship between the fertilizer supplied to a parcel of farmland and the yield, or people's income and demand for certain product can be considered examples.
