摘要
在地震活动性参数估计中 ,对同一地区具有相同地震资料和相同的统计方法情况下 ,关于活动性参数会出现因人而异的估计结果。如何对这些参数的不同估计做出评价 ?对此 ,从统计角度将似然比检验引入到地震活动性参数的不同估计的选优排序决策中 ,分析了似然比检验的基本特征 。
In the estimation of the seismic activity parameters,the different estimated results could be made due to specialists' recognition difference,although they use the same seismic data and mathematical method.How to evaluate these different estimated results?In this paper,the features of likelihood ratio test are discussed statistically.The method of likelihood ratio test is used to evaluate these different estimated results,taking the estimated results in North China as an example.
