Sample Size Calculation for Clustered Binary Data with Sign Tests Using Different Weighting Schemes
We propose a sample size calculation approach for testing a proportion using the weighted sign test when binary observations are dependent within a cluster. Sample size formulas are derived with nonparametric methods using three weighting schemes: equal weights to observations, equal weights to clus...
