In this course you will learn to: 

  • Perform regressions using Python
  • Analyse the strength of correlations
  • Set conditional expectations
  • Analyse the regression line
  • Employ linear models in real-life scenarios 
  • Understand counfounding
  • Perform Lease Squares Estimates
  • Understand association vs causation

  • The correlation coefficient
    • Sample correlation is a random variable
    • Correlation is not always a useful summary
  • Conditional expectations
  • The regression line
    • Regression improves precision
    • Bivariate normal distribution (advanced)
    • Variance explained
    • Warning: there are two regression lines
  • Exercises

Linear models 

  • Case study: Moneyball
    • Sabermetics
    • Baseball basics
    • No awards for BB
    • Base on balls or stolen bases?
