Use Equation (7.6) to create six graphs. In each graph, plot the explanatory variable (x) versus the expected probability of success (p) using b0 = –10 and –5 and b1 = 0.5, 1, and 1.5. Repeat the process for β0 = 10 and 5 and β1 = –0.5, –1, and –1.5.
a. Do not submit the graphs, but explain the impact of changing β0 and β1.
b. For all of these graphs, what value of p appears to have the steepest slope?
Equation 7.6
πi = eβ0 + β1xi / 1 + eβ0 + β1xi
