Regression Analysis-based Chinese Olympic Games Competitive SportsStrength Evaluation Model Research

摘要

The paper mainly applies a weighted accumulative method to predict Chinese previous Olympic Games medalstotal amount and analyze golden medals total amount floating change rule. According to analysis, the paper thinks thatOlympic Games medals change rule can be predicted from three aspects that are Chinese economic strength, number ofChinese participants and Chinese medals amount changes followed by time. And then it establishes planning model thattargets at minimum error amount between predicted value and actual value, by virtue of previous Olympic Games medalsdata, applying regression equation method, it gets every influence factor correlations with amount of medals; through applyingalgebraic calculus, it solves every influence factors weights and then gets medals predicted formula. Use the predictionformula, it solves the amount of medals in 2012, and contrasts with actual amount of medals in 2012, tests formulaaccuracy. Input Olympic Games relevant prediction data in 2016 into formula, and solve Brazil Rio de Janeiro OlympicGames predicted medals amount.
