我们给出了一个一般的改进的分数检验统计量,其nuil分布是卡方到n-1阶,其中n是样本大小。修改后的统计量依赖于完整数据的对数似然导数的联合累积量。一些应用进行了讨论。在考克斯和里德(1987 a)的基础上,我们还导出了Bartlett型修正的一般公式,以改进零渐近分布为卡方分布的检验统计量。
SUMMARY We give a general modified score test statistic whose nuil distribution is chi-squared to order n-1, where n is the sample size. The modified statistic depends on the joint cumulants of log likelihood derivatives for the full data. Some applications are discussed. Following Cox & Reid (1987a) we also derive a general formula for Bartlett-type corrections to improve test statistics whose null asymptotic distributions are chi-squared.
