Valuation on the Revealed Willingness to Pay: On this principle four methods have been developed. In this section we discuss them in some detail. The market price method:
Excerpts from Survival Statistics - an applied statistics book for graduate students.
Most people view the world as consisting of a large number of alternatives. Futures research evolved as a way of examining the alternative futures and identifying the most probable.
Forecasting is designed to help decision making and planning in the present. Forecasts empower people because their use implies that we can modify variables now to alter or be prepared for the future.
A prediction is an invitation to introduce change into a system. There are several assumptions about forecasting: There is no way to state what the future will be with complete certainty. Regardless of the methods that we use there will always be an element of uncertainty until the forecast horizon has come to pass.
There will always be blind spots in forecasts. We cannot, for example, forecast completely new technologies for which there are no existing paradigms. Providing forecasts to policy-makers will help them formulate social policy.
The new social policy, in turn, will affect the future, thus changing the accuracy of the forecast.
Many scholars have proposed a variety of ways to categorize forecasting methodologies. The following classification is a modification of the schema developed by Gordon over two decades ago: Genius forecasting - This method is based on a combination of intuition, insight, and luck.
Psychics and crystal ball readers are the most extreme case of genius forecasting. Their forecasts are based exclusively on intuition. Science fiction writers have sometimes described new technologies with uncanny accuracy. There are many examples where men and women have been remarkable successful at predicting the future.
There are also many examples of wrong forecasts.
The weakness in genius forecasting is that its impossible to recognize a good forecast until the forecast has come to pass. Some psychic individuals are capable of producing consistently accurate forecasts.
Mainstream science generally ignores this fact because the implications are simply to difficult to accept. Our current understanding of reality is not adequate to explain this phenomena. Trend extrapolation - These methods examine trends and cycles in historical data, and then use mathematical techniques to extrapolate to the future.
The assumption of all these techniques is that the forces responsible for creating the past, will continue to operate in the future.
This is often a valid assumption when forecasting short term horizons, but it falls short when creating medium and long term forecasts. The further out we attempt to forecast, the less certain we become of the forecast.
The stability of the environment is the key factor in determining whether trend extrapolation is an appropriate forecasting model. The concept of "developmental inertia" embodies the idea that some items are more easily changed than others. Clothing styles is an example of an area that contains little inertia.
It is difficult to produce reliable mathematical forecasts for clothing. Energy consumption, on the other hand, contains substantial inertia and mathematical techniques work well.Multiple Choice Quiz Questions.
The woman starts taking the birth control pills on about day _____ of the cycle.
With the exception of sterilization, the most effective method of contraception now available is: a. the combination pill b. Norplant c. the mini-pill inhibit testosterone production b. inhibit sperm production c. Modern production methods allow farmers to produce food more efficiently.
And efficiency, by definition, is producing an effect with a minimum amount of waste or effort. It's this efficiency--the result of food technology--that makes food more affordable.
Selection and Application of an Analytical Method JULY MARLAP In this chapter, project method validation is defined as the demonstration of method applicability. Chapter 4 Instructional Methods and Learning Styles bit about accommodating the variability of students through research into instructional methods and learning styles.
If we vary our methods, we have learned, we accommodate a wider range of single method accommodate all learning styles at once. For example, demonstrations or projects. statistics but instead to find practical methods for analyzing data, a strong emphasis has been put on choice of appropriate standard statistical model and statistical.
