Cоnsider the Autо dаtаset cоnsisting of 392 observаtions 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.
