标题[问题] 问卷等二元式资料要怎麽算power跟样本数
时间Mon Sep 1 22:17:14 2008
题目如下:
Please describe the sample size calculation, power anaylysis and statistical
methods to the outcomes that are commonly used in the instruments such as
questionnaire and/or subjective dichotomous response to a sample inferences
research question.
我只知道这种资料的分析方法有Chi-Square test跟logistic regression
可是power跟可达到显着水准的样本数要如何估算我一直找不到,
网路上有calculator,可是我需要公式,版上有高手可以指点一下吗?
小女子无限感激
