Introduction and General Description of the Method of Contingent Valuation Contingent Valuation is a method of estimating the value that a person places on a good. The approach asks people to directly report their willingness to pay WTP to obtain a specified good, or willingness to accept WTA to give up a good, rather than inferring them from observed behaviours in regular market places. Because it creates a hypothetical marketplace in which no actual transactions are made, contingent valuation has been successfully used for commodities that are not exchanged in regular markets, or when it is difficult to observe market transactions under the desired conditions.
Hence a set of factors and factor loadings is unique only up to an orthogonal transformation. Example[ edit ] Suppose a psychologist has the hypothesis that there are two kinds of intelligence"verbal intelligence" and "mathematical intelligence", neither of which is directly observed.
Evidence for the hypothesis is sought in the examination scores from each of 10 different academic fields of students. If each student is chosen randomly from a large populationthen each student's 10 scores are random variables.
The psychologist's hypothesis may say that for each of the 10 academic fields, the score averaged over the group of all students who share some common pair of values for verbal and mathematical "intelligences" is some constant times their level of verbal intelligence plus another constant times their level of mathematical intelligence, i.
The numbers for a particular subject, by which the two kinds of intelligence are multiplied to obtain the expected score, are posited by the hypothesis to be the same for all intelligence level pairs, and are called "factor loading" for this subject.
The numbers 10 and 6 are the factor loadings associated with astronomy. Other academic subjects may have different factor loadings.
Two students assumed to have identical degrees of the latent, unmeasured traits of verbal and mathematical intelligence may have different measured aptitudes in astronomy because individual aptitudes differ from average aptitudes and because of measurement error itself.
Such differences make up what is collectively called the "error" — a statistical term that means the amount by which an individual, as measured, differs from what is average for or predicted by his or her levels of intelligence see errors and residuals in statistics.
The observable data that go into factor analysis would be 10 scores of each of the students, a total of 10, numbers. The factor loadings and levels of the two kinds of intelligence of each student must be inferred from the data.

Retailers have always worked to establish close relationships with customers through the retail marketing mix. Thus, the literature has a long tradition of testing the effects of various instruments on retail patronage. Learn Cost Accounting for Management. Includes Process Costing, ABC Systems, Variance Analysis, Cash Budgets and more.
Variance Analysis: In standard costing, for specified areas of operational activity, the difference between actual & standard costs is known as variances. Types of factor analysis.
Exploratory factor analysis (EFA) is used to identify complex interrelationships among items and group items that are part of unified concepts. The researcher makes no a priori assumptions about relationships among factors..
Confirmatory factor analysis (CFA) is a more complex approach that tests the hypothesis that the items are associated with specific factors. Cost Accounting Managers are in charge for managing cost accounting functions in a company.
