If the model is ln(y)=β0+β1x\ln(y) = \beta_0 + \beta_1 xln(y)=β0+β1x, what is the interpretation of β1\beta_1β1?
A one-unit change in xxx corresponds to a constant unit change in yyy.
A one-unit change in xxx corresponds to a constant percentage change in yyy.
A one-percent change in xxx corresponds to a constant percentage change in yyy.
A one-unit change in xxx corresponds to a constant change in ln(y)\ln(y)ln(y).
