2. Selection of Sufficient Adjustment Sets for Causal Inference : A Comparison of Algorithms and Evaluation Metrics for Structure Learning
University essay from Uppsala universitet/Statistiska institutionenAbstract : Causal graphs are essential tools to find sufficient adjustment sets in observational studies. Subject matter experts can sometimes specify these graphs, but often the dependence structure of the variables, and thus the graph, is unknown even to them. In such cases, structure learning algorithms can be used to learn the graph. READ MORE

3. Evaluating Risk Factors with Regression : A Review and Simulation Study of Current Practices
University essay from Uppsala universitet/Statistiska institutionenAbstract : The term ”risk factor” is used synonymously with both predictor and causal factor, and causal aims of explanatory analyses are rarely stated explicitly. Consequently, the concepts of explaining and predicting are conflated in risk factor research. READ MORE

This is done by balancing the distribution of confounding covariates measured before treatments. READ MORE
