Package: SteppedPower Type: Package Title: Power Calculation for Stepped Wedge Designs Version: 0.4.0 Authors@R: c( person("Philipp", "Mildenberger", role = c("aut", "cre"), email = "pmildenb@uni-mainz.de", comment = c(ORCID = "0000-0002-7367-1708")), person("Federico", "Marini", role = "ctb", email = "marinif@uni-mainz.de", comment = c(ORCID = "0000-0003-3252-7758"))) Description: Tools for power and sample size calculation as well as design diagnostics for longitudinal mixed model settings, with a focus on stepped wedge designs. All calculations are oracle estimates i.e. assume random effect variances to be known (or guessed) in advance. The method is introduced in Hussey and Hughes (2007) , extensions are discussed in Li et al. (2020) .
