Sample Size Determination for Power Analysis Using
Hierarchical Designs
ABSTRACT
In this talk we will discuss how to determine sample sizes for hierarchical mixed-effects models. Both subject-level and site-level randomizations will be considered in this power analysis. We will show how the site-level randomization needs a special consideration to determine the sample sizes to achieve desired power. The impact of dropouts, number of measuring time-points, and variance components will be considered as well in this analysis. Results will be illustrated with a dataset from psychiatry.
