Dear Detleffff,

❝ Ok, maybe that your naming proposal fits your need better. Mine was driven from the term standard deviation of error.

No sir With all due respect, I side with Ben here. I think you should follow common naming conventions.
I am not often using PowerTOST but I think that what you are calling 'standard deviation of error' is no such thing. It is a measure of the standard deviation of the mean difference (on the log scale, for the most common use) and as such it could be termed sd or s, but definitely not Standard Error.
In practice we nned to regard the SD as a variability measure, whereas the SE is a measure of how well we have estimated the mean (slash mean difference). The two are related but different.
