Variables regionalisees et denombrement d'Insectes : cas unidimensionnel Comptes Rendus de l'Academie des Sciences Serial Number : 301, Serie III,9, 1985, pp. 423-428 ISSN : 0764-4469 Key-Words : SYSTEMATIC SAMPLING,REGIONALIZED VARIABLES,INSECTS COUNTING Abstract The accuracy of a systematic sample cannot be calculated within the framework of classical sampling theory. A simple example relating to populations biology (insects counting) is used to show that the transitive theory of regionalized variables allows this calculation. Results are compared with those obtained from sub-sampling simulation within data.
