[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]You ask for a study and one is provided with American defined data.

Just accept reality.[/quote]That's a great chart in showing that a change in the 12 month age range can mitigate RAE but it might be the result of just layering SY and BY RAE on top of each other in the cumulative data. He should do a Fischer's transformation based on birth year on the two populations to test this. Considering he thought SY in 2023 was birthdate cutoff for these players who were up to what 40 years old, he didn't even think of it. It's why you do research on the subject you know with data you know.[/quote]

Have him find a chart of the USYNT rosters.
Because this is what US Soccer says

**The Relative Age Effect (RAE) in US Youth National Team (USYNT) rosters means players born earlier in the cutoff period (e.g., Jan-Mar) get selected due to being physically more mature (bigger/stronger), creating a developmental advantage over later-born players (Aug-Oct) who are often more skilled but overlooked. U.S. Soccer has tried different cutoffs (August 1st to January 1st and back) to lessen RAE and align with school years, but RAE persists, though studies show it's less pronounced in elite YNTs, with later-born, late-maturing players sometimes appearing more in those rosters.

How RAE Affects USYNTs
Selection Bias: Early-born players often seem more talented at younger ages because they are physically bigger and faster, leading coaches to favor them.
Disadvantage for Late Developers: Skilled players born later in the year (e.g., Oct-Dec) get overlooked because they aren't as physically developed as their older peers, potentially losing out on crucial early identification**[/quote]

That's all well and true but Aug guy only likes the study that benefits his anti-rae argument.[/quote]
