aircraft

This dataset is presented in Rousseeuw and Leroy (1987, pp. 154), and the aim is to model the 
 cost of 23 single-engine aircraft (in unit of $100,000) as a function of the following explanatory 
 variables: aspect ratio, lift-to-drag ratio, weight of the plane, in pounds, and maximal thrust.
