[ 1 ] - “Equivalent Linear Composition” as an Efficient Stratification Factor in Multipurpose Surveys
Horticulture survey is a multi-purpose survey which is conducted ad hoc by Statistical Center of Iran (SCI). Availability of survey variables in the sampling frame suggests a multivariate stratification in each province based on its desired variables for acquiring a higher efficiency. There are several ways to stratify the sampling frame considering all stratification variables, such as using s...
[ 2 ] - Calibration Weighting to Compensate for Extreme Values, Non-response and Non-coverage in Labor Force Survey
Frame imperfection, non-response and unequal selection probabilities always affect survey results. In order to compensate for the effects of these problems, Devill and Särndal (1992) introduced a family of estimators called calibration estimators. In these estimators we look for weights that have minimum distance with design weights based on a distance function and satisfy calibration equa...
