Abstract: The k-nearest neighbours (k-NN) method constitutes a possible approach to improve the precision of the Horvitz– Thompson estimator of a single interest variable using auxiliary information at the estimation stage. Improvements are likely to occur when the neighbouring structure in the space of auxiliary variables is similar to the neighbouring structure in the space of the survey variables. Populations suitable for k-NN can be identified via the scores of the first principal component comput
