Toying with OLS III: Model Selection

NixSplash, a water conservationist group in Utah, wants to make a targeted ad campaign to encourage high water consumers to reduce their water usage. To determine who to target with their ad campaign, NixSplash conducts a survey across a random sample of the population. However, the intern who put together NixSplash's survey asked a bunch of odd questions. Use NixSplash's survey dataset, Survey, to generate the best model for predicting a household's water usage.

*** =instructions

  • 1) Examine the data from the survey
  • 2) Build a regression model that includes all statistically significant predictors of a household's water usage (Water).
  • 3) Build a regression model that includes all intuitive predictors of a household's water usage (Water).
  • 4) Decide which way of modeling is better.
