Activity: Life expectancy[edit | edit source]

  • If you're curious about how multiple regression can be applied, complete a Life Expectancy Calculator (takes ~15 minutes). This will use a regression equation (behind the scenes) to predict how long you will live.
  • What could you do to improve your life expectancy? (probably change your behaviour on some of the key predictors)
  • What do you estimate the unstandardised regression coefficients to be for each of the variables the calculator recommends you could change in order to increase your life expectancy?
  • What do you think the an 80% confidence interval would be for your life expectancy estimate? (can be estimated via this very short Life Expectancy Calculator (takes <1 minute).
