Description
Summary:Commonly utilized methods include principal component analysis and common factor analysis[1-4], fuzzy evaluation method), and comprehensive index method. [8] and Huang Weikang et al. employed principal component analysis alongside the fuzzy evaluation method to assess the cold tolerance of cowpea. Subsequently, cluster analysis was performed, and the resources were comprehensively evaluated using several methodologies, including common factor analysis, entropy weight-TOPSIS, grey correlation analysis, and fuzzy evaluation. Furthermore, three plants were randomly chosen from each treatment for the evaluation of pod number and yield per plant. 2.4 Statistical analysis WPS Office software was utilized for various analytical processes, including data collation, fuzzy comprehensive evaluation, grey correlation method comprehensive evaluation, entropy weight-TOPSIS comprehensive evaluation, and comprehensive index method comprehensive evaluation.
