Hello,

  I wanted to conduct a power calculation for sample justification. The study is a cross-sectional study with a predictor variable that is Dichotomous and an outcome variable that is also Dichotomous. How would I calculate the power for sample size justification using a chi-square test on SAS? 

 

Thank you in advance!
