Čestitke Vesni in Teji za današnja fenomenalna dosežka! O olimpijskih medaljah (s poletnih olimpijad) z ekonometričnega vidika pa najdete nekaj tukaj: http://davegiles.blogspot.com/2014/02/modelling-olympic-medal-wins.html#more

Povzetek:
“We model summer Olympic medal counts using count data analysis. The advantage of
this methodology is its explicit recognition of the discrete non-negative form of the
dependent variable; i.e. the total number of medals won by a nation in a summer
Olympiad. Using data from the most recent 2004 Summer Games in Athens, Poisson and
negative binomial count data regression models are constructed. The chosen model is
negative binomial and attaches statistical significance to Gross Domestic Product (GDP)
per capita, the age dependency ratio, and a relatively cold winter climate. In contrast to
previous studies, population, health expenditure per capita, and the effect of being a host
or neighbour nation are all insignificant in explaining medal counts. We also find no
“cricket effect” or “rugby effect.” “
