lultiple Regression Consider the following simple regression model: Model 1: Z = 0, +W + 0,R+V, Researchers think that error variance of the model has the following functional form: E(v)= p W, . Using this information, you are asked to obtain a modified model of wages which would be estimated by OLS procedure without violating the Gauss-Markov assumptions. Explicitly show your work and write down theoretical equation of corresponding transformed model
