statpsych v1.2.0 (Release date: 2022/08/15)

Changes:

• New functions:
  • ci.cramer - Confidence interval for Cramer’s V
  • ci.2x2.mean.bs - Confidence intervals for effects in a 2x2 between-subjects design for means
  • ci.2x2.mean.ws - Confidence intervals for effects in a 2x2 within-subjects design for means
  • ci.2x2.mean.mixed - Confidence intervals for effects in a 2x2 mixed design for means
  • ci.2x2.prop.bs - Confidence intervals for effects in a 2x2 between-subjects design for proportions
  • ci.2x2.prop.mixed - Confidence intervals for effects in a 2x2 mixed design for proportions
  • sim.ci.mean1 – Simulation of confidence interval for a single mean
  • sim.ci.mean2 – Simulation of confidence interval for mean difference in a two-group design
  • sim.ci.mean.ps – Simulation of confidence interval for mean difference in a paired-samples design
  • sim.ci.median1 – Simulation of confidence interval for a single median
  • sim.ci.cor – Simulation of confidence interval for a Pearson correlation
  • sim.ci.spear – Simulation of confidence interval for a Spearman correlation
• Modifications:
  • The ci.prop.ps function now outputs an adjusted point estimate of the proportion difference, as stated in the documentation, rather than an unadjusted estimate
  • The ci.cor, ci.cor2, and ci.cor.dep functions now uses a bias adjustment to reduce the bias of the Fisher transformed correlations
  • The ci.median1 function now uses the same standard error formula as the ci.median2, ci.ratio.median2, and ci.median.ps functions
• Error Correction:
  • Corrected an error for the standard error computation in the ci.indirect function

statpsych v1.1.0 (Release date: 2022/06/30)

Changes:

• New functions:

  • ci.cod2 - Confidence interval for a ratio of dispersion coefficients in a 2-group
  • ci.etasqr - Confidence interval for eta-squared
  • ci.lc.gen.bs - Confidence interval for a linear contrast of parameters in a between-subjects design
  • ci.lc.glm - Confidence interval for a linear contrast of general linear model parameters
  • ci.reliability - Confidence interval for a reliability coefficient
  • ci.rsqr - Confidence interval for squared multiple correlation
  • ci.sign1 - Confidence interval for the parameter of the one-sample sign test
  • ci.slope.mean.bs - Confidence interval for the slope of means in a single-factor design with a quantitative between-subjects factor
  • test.kurtosis - Computes Monte Carlo p-value for test of excess kurtosis
  • test.skew - Computes Monte Carlo p-value for test of skewness
  • test.mono.mean.bs - Test of a monotonic trend in means for an ordered between-subjects factor
  • test.mono.prop.bs - Test of monotonic trend in proportions for an ordered between-subjects
  • etasqr.gen.2way - Computes generalized eta-squared estimates in a two-factor design
• Updated documentation for consistency
• Changed arguments for some functions for consistency
  • size.test.cronbach now takes (alpha, pow, rel, r, h) rather than (alpha, pow, rel, a, h)
  • ci.cronbach now takes (alpha, rel, r, n) rather than (alpha, rel, a, n)
• Changed some of the column names in returned matrixes for consistency:
  • ci.median.ps, the last column is now “COV” rather than “cov”
