Identification with Averaged Data and Implications for Hedonic Regression Studies

چکیده
In the estimation of models with averaged data, weighted least squares is often used and recommended as a way of improving the e¢ciency of the estimator. However, if the size of the di¤erent groups is not conditionally independent of the regressand, consistent estimation may not be possible at all. It is argued that in the case of some leading examples of averaged data regression, consistent estimation is possible using the usual weighted estimator.

متن کاملHedonic Pricing under Uncertainty: A Theoretical Consumer Behavior Model
A model of consumer behavior has been formulated by using an additive utility function and the hedonic pricing approach, in a virtual market. Since, there is a time lag between ordering and purchasing products (goods and services) online and receiving them, it means the consumer makes decision under uncertainty. The level of satisfaction with products with distinctive characteristics is describ...
متن کاملReducing Measurement Error in Nutrition Assessment: Potential Research Implications for Iran
