Testing for Equality of Means with Incomplete Data on One Variable: A Monte Carlo Study
一个变量存在缺失时的均值相等检验:蒙特卡洛研究
This article is concerned with the relative merit of the procedures proposed by Lin [2], Metha and Gurland [3], and Morrison [5] for testing the equality of means of a bivariate normal distribution with correlation ρ and common variance σ2 when some observations on one variable are missing. A Monte Carlo study of the powers and level of significance is conducted. Comparisons among these tests and the paired t test are made. The preferred test is established for each…
