I found the following from an older post that suggests otherwise:   "On SAS-L, I replied, and since folks don't always read both, I tried to recover it from the archive:   This looks like an opportunity to use PROC GLIMMIX, and use of the LINK option. For depth LINK=LOG, and for mass LINK=POWER(0.5). Then in the LSMEANS statement, use the ILINK option, and the final values will include the estimates and their standard errors on both the transformed and original scale. The documentation reports that the standard errors on the inverse lined scale are computed by the delta method."     see: https://communities.sas.com/t5/SAS-Statistical-Procedures/How-to-back-transform-LSMEAN-standard-errors-from-PROC-MIXED/td-p/34301   Art, CEO, AnalystFinder.com ...
