Changes in pwrss v1.2.0

• Added unit tests for all procedures
• Added minimum detectable effects
• Added exact correlation (one sample)
• Added type S and M errors for two-sided tests, available through plot() function
• Added clean.parms, unifying how the input parameters in the results list are returned
• Added further input checks so that all input parameters are checked
• Simplified code in power.z.logistic and power.z.poisson
• Corrected formula for Hsieh et al. (1998) in power.z.logistic
• Added target.effect to determine effect of interest in power.f.ancova

Changes in pwrss v1.0.0

• Addition 1: ANCOVA procedures with means and contrasts (Shieh)
• Addition 2: Exact tests for proportions (Fisher & McNemar)
• Addition 3: Generic binomial test (with plotting feature)
• Addition 4: Dependent correlations (Steiger)
• Addition 5: Effect size conversion functions
• Extension 1: Generic tests handles non-zero null (useful for equivalence and minimum effect testing). Some specific tests also allow non-zero null.
• Extension 2: ANCOVA procedures allow R-squared adjustment (i.e., Keppel and Shieh)
• Consistent function names, population-consistent argument names (Greek notation) and base R consistency
• Rigorous error checks and warnings
• Comprehensive print utility with three-tier verbosity control
• Minor bug fixes to plot() function

Changes in pwrss v0.3.2 (not released to CRAN)

• alternative = “less” now produce correct power rates in pwrss.z.prop() function. Thanks to Leszek Gawarecki for reporting the issue.
• The default for p0 argument in pwrss.chisq.gofit() can now be overwritten. Thanks to Kate Crespi for reporting the issue.
• Type 1 and type 2 error plots show and print correct power estimates for two-tailed tests when effect size is near zero. Thanks to dpnichols811 (GitHub profile handle) and Adrian Olszewski for reporting the issue.
• pwrss.z.corr() print correct errors with alternative = “greater” when in fact it is less (or vice versa). Thanks to Jarrod Hadfield for reporting the issue.
