Have you heard about confounding and modification and would like to learn about it? Or did you click on this link out of curiosity? Then, hold on! This will be a short and precise introduction to understanding confounding and modification in modelling.
Recently, I learnt about confounding and effect modification and the impacts it can have on modelling and interpretation of results. I thought about writing a 3-series article demystifying these concepts including an illustrative example of confounding and effect modification with a case study.
You can read the articles below:
Article 1: Confounding and modification in modelling explained here
Article 2: A case study: Assessing confounding and modification using logistic regression in R here
Article 3: The dangers of extrapolation in modelling here
This repository contains the dataset, R and STATA codes used to perform the analysis explained in the articles.
