chi-square test C. ANOVA D. correlation test 相关知识点: 试题来源: 解析 A。用于比较两组均值的统计检验是 t 检验(t-test)。卡方检验(chi-square test)用于检验分类变量之间的关系;方差分析(ANOVA)用于比较多个组的均值;相关检验(correlation test)用于检验变量之间的相关性。反馈 收藏 ...
compare_means()函数进行t.test时报错——“not enough 'x' observation” compare_means()函数用于比较两个或多个独立样本之间的均值。 compare_means( f, data = mydata, paired =FALSE, method = "t.test") #函数的普遍用法 f : formula,x ~ group形式的公式,其中x是表示数据值的数值变量,group是表示...
would like to calculate the p-value that the means are equal. .svy: mean y .svy: mean y, subpop(Michigan_dummy) Is there a post-estimation test that can compare the survey-based means above? I've also thought of the following, but both compare Michigan to non-Michigan states (not t...
