Animal or plant pathologies: Number of samples to be collected to know with a given precision if a farm is positive
Pathologies animales ou végétales : Nombre de prélèvements à réaliser pour savoir avec une précision donnée si une exploitation est positive
Résumé
The objective of this document is to determine the minimum number of measurement points (or the cardinal of the sample to be collected) necessary to know, with a given precision, if a structure (field crop farming, arboriculture, stockbreeding, forest property) is affected or not by a pathology. We explain the related demonstration, then we display the results obtained in the form of tables and graphs. This allows the reader to understand how these results are obtained, to understand their scope and limits, to check if they correspond to the problem he has to deal with, and possibly to recalculate them taking into account the particularities he is facing.
