6. (10/10) Confounders & conditioning of analyses


Idea: Statistical associations between any two variables generally vary depending on the values taken by other "confounding" variables. We need to take this dependency (or conditionality) into account when using our analyses to make predictions or hypothesize about causes, but how do we decide which variables are relevant and real confounders?


Cases: Immunization levels, Premature mortality in Boston, Hormone replacement therapy (cont.), Birth weight and blood pressure, Control at work and mortality, Mendelian randomization to analyze environmental exposures
