WitrynaSince this is just an ordinary least squares regression, we can easily interpret a regression coefficient, say \ (\beta_1 \), as the expected change in log of \ ( y\) with respect to a one-unit increase in \ (x_1\) holding all other variables at any fixed value, assuming that \ (x_1\) enters the model only as a main effect. Witryna2. Recall that log u − log v = log u / v. So in the "percent change" interpretation, a 1% increase in the ratio of x t and x t − 1 is associated with a b 1 % increase in the ratio of y t and y t − 1. This is a slightly messier case than before, but it's still a percent change in percentage points as above. Let's say x t = 1 and x t − 1 = 2.
