Changes:

  • New functions:

    • ci.mean.fpc -- Computes confidence interval for a mean with a finite population correction
    • ci.prop.fpc -- Computes confidence interval for a proportion with a finite population correction
    • ci.poisson -- Computes confidence interval for a Poisson rate
    • ci.ratio.poisson2 -- Computes confidence interval for a ratio of Poisson rates in a 2-group design
    • ci.bscor -- Computes confidence interval for a biserial correlation
    • pi.cor -- Computes prediction interval for an estimated correlation
    • pi.prop -- Computes prediction interval for an estimated proportion
    • test.cor -- Hypothesis test for a Pearson or partial correlation (for zero or non-zero null hypotheses)
    • test.spear -- Hypothesis test for a Spearman correlation (for zero or non-zero null hypotheses)
    • test.cor2 -- Hypothesis test for a 2-group Pearson or partial correlation difference
    • test.spear2 -- Hypothesis test for a 2-group Spearman correlation difference
    • test.mean -- Hypothesis test for a mean using summary information
    • size.ci.cor2 -- Computes sample size for a 2-group Pearson correlation difference confidence interval
    • size.ci.spear2 -- Computes sample size for a 2-group Spearman correlation difference confidence interval
    • size.ci.tetra -- Computes sample size for a tetrachoric correlation confidence interval
    • size.ci.mean.prior -- Computes sample size for a mean confidence interval using a planning value from a prior study
    • size.ci.prop.prior -- Computes sample size for a proportion confidence interval using a planning value from a prior study
    • size.ci.cor.prior -- Computes sample size for a correlation confidence interval using a planning value from a prior study
    • adj.se -- Computes adjusted standard errors for slope coefficients in an exploratory analysis
    • fitindices -- Computes four SEM fit indices

  • Modifications:

    • ci.var.upper now computes an exact upper limit rather than an approximate upper limit
    • power computations are now more accurate for very small effect sizes in the power.cor, power.cor2, power.lc.meanc.bs, power.mean, power.mean2, power.mean.ps, power.prop, power.pro2, and power.prop.ps functions
    • size.test.prop and size.test.prop2 now assume the test statistic will use a continuity correction
    • one-group function names that end with a "1" have been renamed and now exclude the "1" (for naming consistency and to avoid confusion with lower case L).
    • ci.mape2 has been renamed ci.ratio.mape2, and ci.cod2 has been renamed ci.ratio.cod2
    • The ci.phi function now uses a Fisher transformation for improved coverage probability performance
