metaConvert: an automatic suite for estimation of 11 different effect size measures and flexible conversion across them
A fundamental pillar of science is the estimation of the effect size of associations. However, this task is sometimes difficult and error-prone. To facilitate this process, the R package metaConvert automatically calculates and flexibly converts multiple effect size measures. It applies more than 120 formulas to convert any relevant input data into Cohen's <i>d</i>, Hedges' <i>g</i>, mean difference, odds ratio, risk ratio, incidence rate ratio, correlation coefficient, Fisher's r-to-z transformed correlation coefficient, variability ratio, coefficient of variation ratio, or number needed to treat. Researchers unfamiliar with R can use this software through a browser-based graphical interface (https://metaconvert.org/). We hope this suite will help researchers in the life sciences and other disciplines estimate and convert effect sizes more easily and accurately.
