1
New cards

Level-Level Regression (Y = a + BX)

Y = a + BX

One unit change in X leads to B unit change in Y.

2
New cards

Log-Level Model (LnY = a + BX)

Change in % Y = (100B)(change in X)

One unit change in X leads to 100*B percent change in Y

3
New cards

Level-Log Model (Y = a+(B)(LnX))

Change in Y = (B/100)(% change in X)

One percent change in X leads to B/100 change in Y

4
New cards

Log-Log Model (LnY = a + BLnX)

% change in Y = B(% change in X)

One percent change in X leads to B percent change in Y
