[Analysis of spatial clustering of disease].
It is difficult to determine whether there is spatial clustering of disease if the geographical distribution of population is unknown. Permutation test reported in the paper can be used as a method to judge the spatial clustering with unknown distribution of a random sample of cases. Comparison of difference in frequency of small distances between pairs of cases and controls can show whether there is spatial clustering of the disease.
