Modelos mistos para classificação de jogadores de peteca

Abstract

A simulation study was carried out to evaluate the efficiency of mixed models to represent shuttle pairs toumaments and to rank it's players. In the simulation, the number of pointsof each pair in a singleset game comes from a Poisson distribuition whose mean accomodates effects ofplayers and game in a normal distributed latent variable. Mixed models was compared to the usual form of analysing these toumaments (number ofvictories and point average in case of draws). Mixed model analysis was more correlated with true simmulated values than usual analysis. This difference was more pronounced when response variables were square rooted (variance stabilizing transformation). Results suggest that mixed models can be used to design more effective toumaments.
