Pooled Within-Group Standard Deviation from SE of Raw Mean Difference
IMPORTANT : For a single group, use SD_from_SE !
Calculates the implied pooled within-group standard deviation from the SE of a raw mean difference from two independent groups and their sample sizes. This method is the reverse of SEp_from_SDp under the equal SD assumption.
Do not use with SEs for SMDs, odds ratios, risk ratios, hazard ratios, log effects, adjusted model estimates when reconstructing raw SDs, Welch tests, or paired designs.
