CRAN 0.8.5

effectsize 0.8.5

New features

• interpret_cfi() gains a new rule option: "hu&bentler1999" ( #538 ).
• cohens_f() added option to return unbiased estimators (based on Omega- or Epsilon-squared).
• tschuprows_t() now returns an effect size corrected for small-sample bias. Set adjust = FALSE to preserve old behavior.
• w_to_v() and others for converting between effect sizes of Chi-square tests.
• arr() and nnt() for Absolute Risk Reduction or Number Needed to Treat.
• oddsratio_to_arr(), riskratio_to_arr(), nnt_to_arr() and their inverses.
• logoddsratio_to_*() and *_to_logoddsratio() have been added as convenient shortcuts for oddsratio_to_*(log = TRUE) and *_to_oddsratio(log = TRUE).
• Added all missing functions to convert between (log) OR, RR, ARR, and NNT.

Changes

• fei() gives a more informative error method for invalid table inputs (#566).
• convert_*() aliases are deprecated.

Breaking Changes

• *_to_riskratio() and riskratio_to_*() argument log not longer converts RR to/from log(RR).
• interpret_gfi() and friends: some previously named "default" rules have been re-labelled as "byrne1994".

Bug fixes

• riskratio() returns correct CIs (#584)
• d_to_r() correctly treats specifying only n1/n2 as equal group sizes (#571)
