This report analyses the mtcars dataset (Motor Trend Car Road Tests) from R “datasets” package, and uses multivariate regression model to understand the relationship between miles per gallon(mpg) and various variables. The effects of transmission type are especially interested in. Various techniques are used to help selecting the best fitted regression model. The results show that transmission type has a significant effect on mpg. On average, manual transmission cars get 2.94 miles per gallon more than automatic transmission cars.
