Assignment 5: Checking Statistical Assumptions
The mtcars dataset included in R contains information extracted from the 1974 Motor Trend US magazine, and contains 32 observations of different vehicles (1973-74 models) regarding their fuel consumption data and other 10 car aspects. For this assignment, a multiple linear regression model was built to predict mpg (miles per gallon of fuel), based on cyl (number of cylinders), hp (gross horsepower), wt (weight of the vehicle in lb/1000), qsec (1/4 mile time) and am (transmission: automatic or manual). The predictors were chosen based on an educated guess.
In order to make a diagnosis of this model, several plots Continue reading...
