Hedonic models are most commonly estimated using regression analysis, although some more generalized models such as sales adjustment grids are special cases which do not. An attribute vector, which may be a dummy or panel variable, is assigned to each characteristic or group of characteristics.
The model then provides as output various resources requirements in cost and time. Some models concentrate only on estimating project costs (often a single monetary value). Little attention has been given to the development of models for estimating the amount of resources needed for the different elements that comprise a project. [1]
Note that this is the structural form of the model, showing the relations between the Q and P. The reduced form however can be identified easily. Fisher points out that this problem is fundamental to the model, and not a matter of statistical estimation:
Techno-economic analyses are usually performed using a techno-economic model. A techno-economic model is an integrated process and cost model. It combines elements of process design, process modeling, equipment sizing, capital cost estimation, and operating cost estimation.
Identifiability of the model in the sense of invertibility of the map is equivalent to being able to learn the model's true parameter if the model can be observed indefinitely long. Indeed, if {X t} ⊆ S is the sequence of observations from the model, then by the strong law of large numbers,
The profit model may represent actual data (c), planned data (p)or standard data (s) which is the actual sales quantities at the planned costs. The actual data model will be (using equation 8): π = p c *q c - [F c + (mμ c + lλ c + n c)q c] The planned data model will be (using equation 8): π = p p *q p - [F p + (mμ p + lλ p + n p)q p]
CVP is a short run, marginal analysis: it assumes that unit variable costs and unit revenues are constant, which is appropriate for small deviations from current production and sales, and assumes a neat division between fixed costs and variable costs, though in the long run all costs are variable.
Example Van Westendorp questionnaire. The traditional PSM approach asks four price-related questions, which are then evaluated as a series of four cumulative distributions, one distribution for each question. The standard question formats can vary, but generally take the following form:
