selecting travel trailers by regression

Data Scientist has been thinking recently of moving into a used travel trailer. However, the weight of the trailer to be purchased is limited by that which our hero’s truck can pull. But most online used travel trailer listings only specify length of the vehicle, not its weight. So Data Scientist needed a quick way to estimate the weight based on length. Enter regression analysis:


Our hero found 21 new trailer listings [1,2] and recorded their dry (tanks empty) weight and length. Data Scientist then performed regression analysis on these known weights and lengths to obtain an equation for estimating weight based on advertised length. Using this equation, our hero minimizes trips to go inspect potential purchases by ruling out cases most likely to exceed the weight limit.
