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
