Predictions after mean-centred regression

#1
Hi, I wonder if anyone can help me with a problem I'm having.

I just performed an ordinary (LS) regression in which both the dependent and independent variables were logged (the model is log-linear) and grand-mean-centred. The results look good. However, for my purposes, I need to be able to conjure up predicted values of (non-mean-centred) Y. How do I do this, given the mean-centring?

Thanks in advance,

Charlie

So all variables (independent and dependent) were logged then mean-centered? Curious how many independent variables you had?
