When working today about COVID-19 mortality, I was falling back to the survivorship bias that is nice illustrated at Wikipedia and which is just another type of selection bias that I explained in my last talk.<\/p>\n
During World War II, the statistician\u00a0Abraham Wald took survivorship bias into his calculations when considering how to minimize bomber losses to enemy fire.The Statistical Research Group (SRG) at\u00a0Columbia University, which Wald was a part of, examined the damage done to aircraft that had returned from missions and recommended adding armor to the areas that showed the least damage, based on his reasoning. This contradicted the US military’s conclusions that the\u00a0most-hit<\/i>\u00a0areas of the plane needed additional armor.<\/sup><\/p><\/blockquote>\n\n <\/p>\n
