This article provides a comprehensive overview of advanced causal inference methods, moving beyond traditional statistical approaches. It emphasizes the importance of understanding causal relationships rather than just correlations for effective decision-making. The playbook covers techniques like instrumental variables, regression discontinuity, difference-in-differences, and causal discovery algorithms.
It discusses the assumptions required for each method and how to validate them. The author stresses the need for careful consideration of confounding variables and potential biases when attempting to establish causality. Ultimately, the article aims to equip data scientists with the tools and knowledge to draw more meaningful and actionable insights from data.

This article explores the power of causal inference as a method for quantifying the impact of actions and improving decision-making, particularly in comparison to traditional A/B testing. It details how causal inference can provide a deeper understanding of customer behavior by estimating the individual impact of treatments (like marketing campaigns) and addressing the limitations of A/B testing, such as treating customer variability as noise and requiring large sample sizes. The article highlights applications in marketing, product recommendations, and customer retention, emphasizing benefits like customer segmentation, more precise estimates, and real-time learning. Ultimately, it argues that embracing causal inference can lead to more effective testing, optimized customer experiences, and shorter test cycles.

The article discusses methods for data scientists to answer 'what if' questions regarding the impact of actions or events without having conducted prior experiments. It focuses on creating counterfactual predictions using machine learning techniques and compares a proposed method with Google's Causal Impact. The approach involves using historical data and control groups to estimate the effect of modifications, addressing challenges such as seasonality, confounders, and temporal drift.
This article explains how adding monotonic constraints to traditional ML models can make them more reliable for causal inference, illustrated with a real estate example.
This article discusses the differences between predictive and causal inference, explains why correlation does not imply causation, and why machine learning is not inherently suited for causal inference. It highlights the limitations of using machine learning for causal estimation and provides suggestions for when each type of inference should be used. The article also touches on causal machine learning and its role in addressing the challenges of high-dimensional data and complex functional forms.
Exploring and exploiting the seemingly innocent theorem behind Double Machine Learning. The theorem, rooted in econometrics, states that if we have a linear model that predicts an outcome variable based on multiple features, and we want to understand the causal effect of a specific feature on the outcome, we can use the residuals of the model as an instrumental variable to estimate the causal effect.
This article discusses causal inference, an emerging field in machine learning that goes beyond predicting what could happen to focus on understanding the cause-and-effect relationships in data. The author explains how to detect and fix errors in a directed acyclic graph (DAG) to make it a valid representation of the underlying data.
