Conducting power analyses for ANOVA and ANCOVA in between-subjects designs.Researchers are frequently asked to justify the sample size used in their quantitative inquiries. Such a justification can be provided through a power analysis. Conducting power analyses, however, can raise some difficult issues...

R语言入门之效力分析(Power Analysis) 1. Power Analysis前言 效力分析是实验设计阶段非常重要的一部分内容,它主要是帮助我们确定在指定显著性条件下实验所需要的样本量并评估该实验设计的统计效力。通过效力分析,我们也能给出在现有的样本量下该实验结论的可靠性。如果结论的可靠性非常低,那么几乎可以宣布这个实验是...
There are numerous published sources that address statistical theory and applications of power analysis for ANOVA and multiple linear regression. Specifically, various algorithms and tables for power and sample size calculations in ANOVA have been presented in the classic sources of Bratcher et al. (...

We introduce new methods for power analysis and sample size planning that can be applied when marginal maximum likelihood estimation is used. This allows the application to a variety of IRT models, which are commonly used in practice, e.g., in large-scale educational assessments. An analytical ...
