INSTRUMENTAL VARIABLE ANALYSES EXPLAINED - 5-minute mini epidemiology-tutorial for beginners

In this short tutorial I will teach you what an instrumental variable is and how you can use it in your own data. Instrumental variable analyses can solve the problem of confounding by indication and are helpful when you are comparing treatment effects in observational data.

Dear Dr. de Glas,
Could you please produce a video with a real or simulated analysis using instrumental variables? I believe that many followers, me included, will be very grateful. Thank you.
