Simulated data for the study is saved inthe file. In Exercise 12.17, you fit the first-order model,E(y) = β0 + β1x1 + β2x2 + β3x3 + β4x4, where y = desireto have cosmetic surgery,x1 is a dummy variable for gender,x2 = level of self-esteem, x3 = level of body satisfaction,and x4 = impression of reality TV.
