Chapter 4. The Unreasonable Effectiveness of Linear Regression In this chapter you’ll add the first major debiasing technique in your causal inference arsenal: linear regression or ordinary least squares (OLS) … - Selection from Causal Inference in Py
The concept of machine learning has somewhat become a fad as late, with companies from small start-ups to large enterprises screaming to be technologically enabled through the quote on quote, integration of complex automation and predictive analysis. Companies Mentioned Coin Mentioned ...

that does not involve adding any further variables to the regression but will make a causal interpretation of the unemployment coefficient more plausible? Can you implement this? Report and discuss the results. [4 points] Question 3 (20 points) ...
these two models should be an interpretable model (e.g. OLS, subset selection, Lasso, Ridge, Elastic net, a single regression tree), and the second one should be a more advanced model (bagging, random forests, boosting, or a model that contains one of these three as a part). ...

For the estimation results to have a causal interpretation, some methods assume no unobserved confounders (i.e. there is no unobserved variable not included in X, W that simultaneously has an effect on both T and Y), while others assume access to an instrument Z (i.e. an observed ...
