14.2.4 Linear-Log model. Or logarithmic model. y =β0 +β1logx+ϵ. (14.15) (14.15) y = β 0 + β 1 log x + ϵ. This is just a logarithmic transform of explanatory variable. The parameter β1 β 1 in this case regulates the direction and speed of change. If x x increases by 1%, then y y will change on average by β1 100 β 1 100 units.
