• New functions:

    * ci.cv1 -- Computes confidence interval for a single coefficient of variation
  
    * ci.ratio.cv2 -- Computes confidence interval for a ratio of coefficients of variation
  
    * ci.pv -- Computes confidence intervals for positive and negative predictive values with
      retrospective sampling
  
    * ci.2x2.stdmean.ws -- Computes confidence intervals of standardized effects in a 2x2 
      within-subjects design
  
    * ci.2x2.stdmean.mixed -- Computes confidence intervals of standardized effects in a 2x2 
      mixed design
  
    * ci.2x2.median.ws -- Computes confidence intervals of effects in a 2x2 within-subjects 
      design for medians
  
    * ci.2x2.median.mixed -- Computes confidence intervals of effects in a 2x2 mixed design  
      for medians
  
    * spearmanbrown -- Computes the reliability of a scale with r2 measurements given the 
      reliability of a scale with r1 measurements
  
    * size.ci.spear -- Computes the sample size requirement for a Spearman correlation confidence interval
  
    * size.ci.pbcor -- Computes the sample size requirement for a point-biserial correlation confidence interval
  
    * size.ci.mape1 -- Computes the sample size requirement for a mean absolute prediction error confidence interval
  

• Error Corrections:

     * corrected CI error in ci.cramer
  
     * corrected SE error in ci.lc.stdmean.ws
  

• Modifications:

     * both biased and bias adjusted estimates are now reported in ci.stdmean1, ci.stdmean2, 
       ci.stdmean.ps, ci.stdmean.strat, and ci.2x2.stdmean.bs
  
     * ci.mape has been renamed ci.mape1
