| Does air quality affect mortality? | What will the mortality be in the future? |
Mortality
=========================================================
Particluate matter with diameter less 10μm (PM10)
=========================================================
Simple scatter plot: no correlation
=========================================================
Confounding variables: example
=========================================================

=========================================================
Multiple linear regression I
=========================================================
Multiple linear regression II
=========================================================
Prediction: feature importance
