Companies need to measure the impact of their decisions. Nowadays, digital companies can evaluate many options by running A/B tests on their websites or apps. Unfortunately, A/B tests have limitations: sometimes, they are too expensive or not ethical or even impossible! Moreover, companies already have historical data, and they want to consider it too. When data has been obtained through observations, instead of A/B tests, its analysis can easily fall into many traps and get the wrong conclusions. Causal inference is both a methodology and a toolkit that guides you through the analysis to avoid them. Aleix will demonstrate on a set of simple use cases how causal inference can be applied to marketing, COVID-19, measuring worker's effectiveness and pricing.If you are already interested check this article and this video.
