Automobile efficiency across eras
I started with the UCI Auto MPG dataset, then added newer EPA and NRCan data to see how well fuel-economy models carry from one vehicle era to another.
The notebooks contain the full analysis. These pages are the parts I wanted to make interactive.
Pages
I kept the sources separate where their variables or units do not match.
Prediction models
Try the fitted models using the variables available in each source dataset.
Long-run trendsFollow annual EPA fuel economy, vehicle mix, and powertrain changes.
Drift and residualsCompare errors when a model is tested on a different vehicle period.
Data notesSee what each file contains, its year range, and how I use it.
