I am fairly new to regression and have been set the task of modelling a data set in the form ln(y) = bx1 +bx2 +bx3 +bx4 +bx5 + e.

In the regression output the coefficient value of b range from -0.081 to 0.61. I understand, that for b1=0.61, that a 1 unit increase in x1 will result in a 0.61 increase in ln(y). Using exp(0.61)=1.84, I have interpreted this as a 84% increase in y. For negative coefficients, there seems to be some indication of a different process - can anyone shed any light on this for me?

At the moment, for x3=-0.081, I have used exp(-0.081)=0.92, indicating a 8% decrease in y for every unit change in x. Is this correct?

Am I approaching this regression output in the correct way? Any advise would really be helpful and much appreciated.

Many Thanks,

Adam
