Abstract
The negative hyper-geometric distribution was introduced to describe the spatial pattern of disease infection or insect infestation among plant individuals in the field. This model contains two parameters, one of which, α, can be used as the same dispersion measure as κ in the negative binomial distribution, α has a close relation with MORISITA's (1959, 1962) indices. The negative hyper-geometric distridution generates the negative binomial, binomial and Poisson distributions as its special cases. It was used for a study of the spatial pattern of yellow dwarf disease of rice plants.
