| Abstract: |
| 【Objective】 The aim of this study was to conduct the necessity and significance of the model selection criterion AIC in ANOVA selection.【Method】 This study introduced the conception of model selection criterion AIC briefly,deduced AIC formula in ANOVA model selection and applied AIC to select the best ANOVA model in rice variety comparison trail data.【Result】 ANOVA model selection was necessary in the 5 rice varieties comparison trial data.AIC was a simple and effective method in ANOVA model selection.【Conclusion】AIC could be used to select the best model of ANOVA and improve the credibility of the ANOVA conclusion. |
