| Abstract: |
| 对构成双向有序列联表时间序列数据的广东 1984～ 1993年 10年乙型脑炎 (乙脑 )逐月发病资料,应用游程检验和有序对数比检验两种不同统计方法进行季节性分布分析,获一致的统计结论,乙脑发病呈明显的一年一峰 ( 6月或 7月 )季节性周期,这对流行病学工作者掌握两种统计方法的基本原理和方法有一定帮助。 |

| This paper analysed the data of epidemicencephalit is Bincidence that was constitutedto time- series and the two-ordered conting encytable in Guang dong province from 1984 to1993. Two different kinds of statistical methods of run- test and ordered-log-ratio test were applied to study the characteristics of seasonal distribution. Consistent conclusion was obtained to showthat there appeared an obvious seasonal cyclic characteristic of a peak every year ( June o r July ) for the incidence of epidemic encephalitis B. It is helpful for the epidemiolo gists to under stand the principle and method of these statistical tests. |
