Forecasting the Olympic medal distribution – A socioeconomic machine learning model
2022, Technological Forecasting and Social ChangeCitation Excerpt :First, by increasing the level of granularity beyond country-specifics; second, by including more years; and third, by exploring additional independent variables. As a common way to incorporate more granular data, and thus to increase the forecast accuracy, some authors considered predicting the Olympic success by focussing on different sports (e.g. Tcha and Pershin, 2003; Noland and Stahler, 2016a; Vagenas and Palaiothodorou, 2019), sometimes even exploring data on the level of the individual athlete (Condon et al., 1999; Johnson and Ali, 2004). Due to the increasing relevance of gender studies, other authors have begun differentiating their data sets by gender (Leeds and Leeds, 2012; Lowen et al., 2016; Noland and Stahler, 2016b).
Multicultural managers and competitive advantage: Evidence from elite football teams
2019, International Business ReviewCitation Excerpt :Country population influences the size of the pool of available athletes for a team. Population is an important determinant of success in the Olympic Summer Games (Condon, Golden, & Wasil, 1999; Szymanski, 2000) and association football (Hoffmann, Ging, & Ramasamy, 2002). Gross domestic product per capita is an indicator of the economic potential of the country, which is necessary for developing elite sport talent.

2012, Sport Management ReviewCitation Excerpt :As too complex regression models tend to increase variances in the coefficients and the predictions, while oversimplified ones suffer from biased coefficients and predictions (Myers, 1990, pp. 178–180), the main methodological problem in this area has been the determination of optimal specifications. When a large number of candidate correlates of Olympic success are explored, some of them end-up to simply be distal covariates of minor or no relevance, as for example correlates such as expected life span, death rate, number of airports, and total railway length found in study (Condon et al., 1999). On the other hand, there are cases of studies in which oversimplified models of Olympic success are proposed with only two predictors (population & GDP), as for example the multiplicative function of Morton (2002) and the ordered-logit model of Andreff (2001), or even with solely one predictor (GNP), as the simplest ever published model proposed by Nevill and Stead (2003).
