Detailed Explanation of Partialling-Out and the Frisch-Waugh-Lovell (FWL) Theorem
Partialling-Out Partialling-out is a technique used in regression analysis to isolate the effect of a specific variable (regressor) on the outcome by removing the influence of other variables (control variables). This helps us understand the true relationship between the target regressor and the outcome. Summary

Regression and the Best Linear Prediction Problem Linear regression is a method for predicting a dependent variable (Y) using one or more independent variables (X). Here’s a simplified breakdown: Practical Implications: Best Linear Approximation Property This property indicates that our best linear prediction (β′X) is also the best linear approximation to the conditional expectation of…
