Hi all,

I conducted a linear regression where the dependent variable (measured as a percentage) is squared root transformed. The independent variables are categorical.

See below for the syntax

generate sqrtdepend=sqrt(dependent)
regress sqrtdepend i.indep1 i.indep2 i.indep3 i.indep4

Now I want back transform the coefficients relative to a predetermined reference level of the dependent variable so that the effect estimates can be directedly compared between variables (the reference value of the dependent variable is 30%).

The formula to do this is below.
2β*301/2 + β2

* β (regression coefficients) refer to differences in square-root values

Any help on how to write the syntax in stata for the above formula?

Thanks in advance for your help.
