The Study Of Main Principal Analysis And Factor Analysis Applied In Sports Research

Based on the former research of main principal analysis and factor analysis for application, this thesis generalize the common method of main principal analysis and factor analysis applied in sports research, comprehensively and systematically analyze several amendment method and problem about the application of main principal analysis and factor analysis, which is worth paying more attention, and conclude main step for application of main principal analysis and factor analysis in sports research.The correlation matrix is the premise for main principal analysis and factor analysis. The factor affecting the correlation is sure to influence the applicative effect of main principal analysis and factor analysis. Initiatively, comprehensively and systematically analyze the affecting factor of Pearson correlation, often used in main principal analysis and factor analysis, enhance the effect of main principal analysis and factor analysis in sports research. Originally define recognition data, discover and amend the problem existing in the main principal analysis and factor analysis. Initiatively offer the main principal analysis and factor analysis under the Kendell's correlation, dissolve the influence of non-normal in recognition data on the main principal analysis and factor analysis applied in sports research.
