Description

Originally posted on https://github.com/easystats/parameters/issues/655

@bwiernik:

Strictly speaking, both the p values and CIs we currently report for standardized effects aren't strictly accurate because they don't include uncertainty in the means or SDs used to standardize. This is usually ignored by most folks. But, ideally we would include options to compute CIs accounting for those (cf. here and here).

@strengejacke

The supplemental (https://static-content.springer.com/esm/art%3A10.1007%2Fs11336-013-9380-y/MediaObjects/11336_2013_9380_MOESM2_ESM.pdf) has code how to do this, if I understand right. Must take a closer look at it.

Research direction

Start by locating the existing standardized-effect confidence-interval and p-value calculations in the R package, then compare them with the supplemental code linked in the issue. Done means providing a defined way to calculate intervals and p-values that account for uncertainty in the means and standard deviations used for standardization.
