In multilevel analyses, it is often necessary to estimate a standardised mean difference (SMD) where the numerator is a covariate-adjusted mean difference and the denominator is the SD from a model without covariate adjustment.
I’m aware of two (frequentist, non-bootstrap) packages calculating an SMD and confidence interval in R. Here’s a comparison of them for simulated data.
