What is forecasting? Explain the different techniques of forecasting?
Solution
Forecasting is the process of estimating the relevant events of future, based on the analysis of
their past and present behaviour.
Techniques of Forecasting:
There are various methods of forecasting. Some of them are:
1. Historical Analogy Method: Under this method, forecast in regard to a particular situation is
based on some analogous conditions elsewhere in the past. The economic situation of a country
can be predicted by making comparison with the advanced countries at a particular stage through
which the country is presently passing.
2. Survey Method:
Surveys can be conducted to gather information on the intentions of the concerned people.
3. Opinion Poll:
Opinion poll is conducted to assess the opinion of the experienced persons and experts in the
particular field whose views carry a lot of weight.
4. Business Barometers:
A barometer is used to measure the atmospheric pressure. In the same way, index numbers are
used to measure the state of an economy between two or more periods. These index numbers are
the device to study the trends, seasonal fluctuations, cyclical movements, and irregular
fluctuations.
5. Time Series Analysis:
Time series analysis involves decomposition of historical series into its various components, viz.
trend, seasonal variances, cyclical variations, and random variances. When the various
components of a time series are separated, the variation of a particular situation, the subject
under study, can be known over the period of time and projection can be made about the future.
6. Regression Analysis:
Regression analysis is meant to disclose the relative movements of two or more inter-related
series. It is used to estimate the changes in one variable as a result of specified changes in other
variable or variables. In economic and business situations, a number of factors affect a business
activity simultaneously.
7. Input-Output Analysis:
According to this method, a forecast of output is based on given input if relationship between
input and output is known. Similarly, input requirement can be forecast on the basis of final
output with a given input-output relationship. The basis of this technique is that the various
sectors of economy are inter-related and such inter-relationships are well-established.
