      design for medians
    • pi.var.upper -- Computes upper prediction limit for an estimated variance
    • ci.bayes.normal -- Computes Bayesian credible interval for any parameter estimator with
      a normal sampling distributuion using a Normal prior distribution
    • ci.bayes.prop1 -- Computes Bayesian credible interval for a single proportion using a Beta
      prior distribution
  • Modifications:
    • Corrected Example output in ci.reliability and ci.prop.ps
    • SE added to output in: ci.cronbach, ci.oddsratio, ci.yule, ci.etasqr, ci.rsqr, ci.spear2,
      ci.cor2, ci.cor.dep, ci.cod1, ci.mad1, ci.mape, ci.agree2, ci.pbcor, and ci.tetra
    • Improved accuracy in size.ci.rsqr
    • Three generalized Yule coefficients added to ci.yule
    • The ci.prop.ps, ci.ratio.prop.ps, and ci.2x2.prop.mixed functions now define proportions
      for the y = 1 category rather than the y = 0 category.
