Abstract: Sample coordination seeks to create a probabilistic dependence between two or more samples. The goal is to maximize the number of common units (positive coordination) to improve the estimation precision or to minimize this number (negative coordination) to reduce the nonresponse rate of units involved in different surveys. The sample coordination is applied in spatial sampling and it is achieved using permanent random numbers. The goal is to coordinate spatial samples, while preserving their good spatial properties. The overall approach is motivated by examples from official statistics and forestry.
