Adding Effect Sizes for Tests

[benediktclaus]

This package is great! One can't think of living without it after exploring it.
However, it would be nice to not just add p-balues, but also effect sizes for group differences/statistical tests.

For continuous variables, these could be Cohen's d and Hedges' g.
For categorical variables, these could be Cohen's w, Cramer's V.
For ANOVAs, these could be Cohen's f, η²_part, and ω²

One can imagine a function like add_effsize()

Hello @benediktclaus ! Thank you for the kind words.

Making these additions simple is on the horizon, but has yet to be implemented. You can follow the progress by subscribing to this issue #617

In the meantime, you can use the function add_stat() to add any statistic you'd like to a tbl_summary() object. Here's an example how to include Cohen's D.

Hope this helps! Happy Programming! 🕺

Ooops, I neglected to paste the link to the example!
