• 1. Conditional and unconditional analysis of some small area estimators in complex sampling Archived

  Articles and reports: 12-001-X20030016608

  Description:

  This work deals with the unconditional and conditional properties of some well-known small area estimators: expansion, post-stratified ratio, synthetic, composite, sample size dependent and the empirical best linear unbiased predictor (EBLUP). A two-stage sampling design is considered as it is commonly used in household surveys conducted by the National Statistics Institute of Italy. An evaluation is carried out through a simulation based on 1991 Italian census data. The small areas considered are the local labour market areas, which are unplanned domains that cut across the boundaries of the design strata.

• 2. Estimation of simple and correlated measurement variance when first and second interview use different survey modes Archived

  Articles and reports: 11-522-X20010016309

  Description:

  This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.

  This paper proposes a method for estimating simple and correlated measurement variance components when a re-interview is available for a subsample of respondents. However, the two measurements cannot be considered as being collected under the same conditions and, therefore, are subject to different measurement error variance. This consideration seems more realistic when, in actuality, it is impossible to ensure that the same measurement conditions are implemented in the two interviews, as in the case when operational and budget constraints suggest adopting a different survey mode for the second interview.
