(d) Regression investigation: This is the most popular method of forecasting demand. The equation will be of the form Y = a + bX. There could also be a curvilinear relationship between the dependent and independent variables. Once the regression equation is derived, the value of Y i.e. quantity demanded can be estimated for any given value of X.
Such as, some other costs might possibly be in the various other conversion process as well as on you to definitely foundation the purchase price-numbers matchmaking try estimated when it comes to regression picture and you can employed for anticipating objectives
Under this method, future demand is estimated by conducting market studies and experiments on consumer behaviour under actual, though controlled, market conditions.

These procedures are derived from earlier experience and then try to investment the past into the future. Particularly projection isn’t active where there are financial ups and you may downs. As previously mentioned over, new projection out of pattern do not suggest the latest turning part away from slump to recuperation otherwise out-of growth to help you recession. Thus, in order to find out such turning items, it is necessary to find out the overall conduct of your savings.
