visStatistics 0.1.2

News

• Added vignette visStatistics.Rmd documenting the statistical decision logic and illustrating each case with reproducible examples.
• Added graphical summary of decision logic to README and vignette

Improvements

• Extended README.html and the @details section of the main function visstat():
  • More precise parameter descriptions and clearer presentation of the decision logic.

Change in decision logic

• Welch’s t-test (t.test()) is now applied when both groups have more than 30 observations (previous threshold was 100).

Bug fixes

• Confidence and prediction bands in regression now depend on the specified conf.level instead of always defaulting to 0.95.
• Post hoc analysis in Kruskal-Wallis test (pairwise.wilcox.test()) now uses the specified conf.level instead of always defaulting to 0.95.
• Switching to fisher.test() now correctly follows expected cell count thresholds.
