查询词典 chi square distribution

Actually, such a generalized Cauchy distribution was the Pearson VII probability distribution. In this dissertation, the Lorentz distribution was regarded as a generalized Cauchy distribution with only one scale parameter; while the Pearson VII distribution was regarded as a generalized Cauchy distribution with a scale and a shape parameter both.

Spatial distribution pattern of larvae of Aleurocanthus spiniferus in citus garden was studied by means of some distribution parameters such as mean crowding, David and Moor's clustering index, index of patchiness, proliferation index, the distribution of negative binomial, Iwao's patchiness, the and Taylor's law. The results showed that the spatial distribution pattern of larvae under all densities appeared to be aggregation distribution, which is characterized by individual attraction and predominant individual group such as cored distribution pattern.
