Tools for Designing and Weighting Survey Samples

Functions and datasets to support Valliant, Dever, and Kreuter, ``Practical Tools for Designing and Weighting Survey Samples'' (2nd edition, 2018). Contains functions for sample size calculation for survey samples using stratified or clustered one-, two-, and three-stage sample designs. Other functions compute variance components for multistage designs and sample sizes in two-phase designs. A number of example data sets are included.
