Format
A data frame with 87 observations of 4 variables
- day_no_dual
Day of the year, adjusted to the country the player grew up in.
- count
Number of births
- t_b_dual
(day_no_dual - 0.5)/365
This data is used to investigate the relative age effect in soccer. From the authors: "Relative Age Effects (RAEs) occur when schools and sports group children into age-banded cohorts. Within each cohort, older children study and compete at an artificially conferred advantage over younger children [1–3]. Since the start-points and end-points for age-bandings rarely change, such advantages are conferred consistently throughout childhood. Initial success tends to breed longer-term success for two good reasons."
