How many medals will each country win in Rio at this Summer's Olympic Games? Researchers who derived predictions from two different models anticipate that the USA, China, Russia, and the UK will retain their top positions in the medals ranking, but Brazil and Japan are expected to make the biggest gains.
As described in a new Significance article, the first model primarily describes a country's medals as a function of the number of medals won at the previous Olympic Games, and the second model includes additional socio-economic variables.
