A Math-Free Workshop for Power Calculation

Sample size calculation plays an important role in study design and grant proposal preparation. An overview of power analysis will be given. Two case studies will be presented to demonstrate the magic of power calculation for the survival model and the linear mixed effect model using SAS and R.


  1. Basic elements of power analysis
  2. Design of a survival study based on the Log-Rank test
  3. The linear mixed effect model: a path for designing a longitudinal study
