Consider the Auto dataset consisting of 392 observations on 9 variables Mpg: miles per gallonCylinders: Number of cylinders between 4 and 8Displacement: Engine displacement (cu. inches)Horsepower: Engine horsepowerWeight: Vehicle weight (lbs.)Acceleration: Time to accelerate from 0 to 60 mph (sec.)Year: Model year (modulo 100) Origin: Origin of car (1. American, 2. European, 3. Japanese) Name: Vehicle nameMpg01: 1 if mpg above median mpg, 0 otherwise We wish to predict whether a given car gets high or low gas mileage (mpg01). We used LDA on train data to predict mpg01.

Suppose n=2, p=2, x11=x12, x21=x22 and y1+y2=0 and x11+x21=0 and x12+x22 =0. Write out analytically the lasso optimization problem in this setting. HINT. Start with the general lasso objective function. Since p=2 write the prediction for observation i using the two predictors. Then expand the summation for n=2. You do not need to solve for the betas.
