Dear in statlist



Quick question of how practically  predict or substitute in the estimated time-series model:

Ln(y) = 3.5 + .55 Ln(X1t) - .95 Ln(X2t) + .6 (dummy)


I know I have to take the exponential of the two sides to get rid of the logarithm, 

Y = EXP [3.5 + .55 Ln(X1t) - .95 Ln(X2t) + .6 (dummy)]

but how the final equation (which I will substitute in it in practice)? 

And Is there a use of geometric mean of (x) for example?



Regards

Talal
