Each of these Graphs were constructed from a series of continuous Data, X (horizontal Axis), a series of discrete binary (dummy) data, D and a continuous dependent variable, Y (vertical axis). The regression model is as follows y = Bo + BIX + BzD + B=(X * D) + u The Orange Line is the expectation when D= 0 given X, and the blue line is expectation when D = 1 given X. Find each coefficient for the following graphs. 50 40 10 5 10 15 20 25 Bo = B1 = BZ = B3 =
