[Feature Request]: Bayesian Credible Intervals specified in raw units #1883

Closed Masharipov closed 9 months ago

Masharipov commented 2 years ago

Description

JASP reports credible intervals in Cohen's d values. Is would be great to get 95% credible intervals in both raw units and Cohen's d (in plots and tables) in future releases.

Purpose

1) To see the posterior probability distribution in both raw and Cohen's d units. 2) To perform Bayesian parameter inference on raw units.

In some scientific field the raw units may have more sense than Cohen's d units. For example, heart rate, blood pressure or BOLD signal change have better interpretability in raw units. For example, one would like to see if the 95% Credible Interval (or Higher density interval) of the BOLD signal change fall within or outside the region of practical equivalence (ROPE) (i.e. [-0.01:0.01] BOLD signal change %). This procedure refers to the "HDI+ROPE" decision rule described in Kruschke (2018).

Use-case

Hi @Masharipov, thanks for the request. This seems reasonable to me. How feasible is it @vandenman?
