Betreff: st: FW: Transformation of SE
Dear All,
I run regression and used a log transformation to normalize the
distribution of variables and meet other regression assumptions.
I got predicted values that I need to transform (antilog) using Duan's
Smearing Retransformation and stdp standard error of the linear
prediction xb which a I would use eventually to calculate ub and lb.
reg lnX lnY lnZ
predict yhatraw
predict SE, stdp
gen YHTSMEAR=(exp(yhatraw))*meanres
My question is what to do with SE. How can I transform it after I do
antilog of predicted values using Duan's Smearing Retransformation?
Thank you in advance
Dejan
