Price Imputation and Other Techniques for Dealing with Missing Observations, Seasonality and Quality Change in Price Indices / Paul Armknecht Jr., Fenella Maitland-Smith.

Incorrect treatment of such situations can result in biased price indices. This paper presents statistical imputation techniques that index compilers can use to prevent bias and suggests the extension of these same techniques to assist with adjustments for quality differences. The use of additional procedures for dealing with some of the problems caused by seasonal commodities is also discussed. Mode of access: Internet Maitland-Smith, Fenella.
