Hi all,


I have conducted a linear regression where outcome measures were square-root transformed (one of them is measured as a percentage and the other is measured as centimetres squared) to improve the normality of the residuals.

Now, I want to back transform the coefficients relative to a predetermined reference level of 25% for the percentage variable and 140 cm2 for centimetres squared variable. I am not sure how to do this.

Any help with this will be highly appreciated.
