2.1 Projects

Think about your bachelor’s and master’s projects that involved statistics. What was the topic? Was the aim to explore, predict or infer? What was the main statistical technique used? We will discuss this in class.

2.2 Confounder

Modest alcohol drinking compared to non-alcohol drinking is associated with a higher life expectancy. See for example this figure of the article

Liu, YT., Lee, J.H., Tsai, M.K. et al. The effects of modest drinking on life expectancy and mortality risks: a population-based cohort study. Sci Rep 12, 7476 (2022). 10.1038/s41598-022-11427-x

Do you think that there are confounders in this association? If yes, what are they?
