同学你好,
原版书的定义:
djusted R2 is used as a measure of model goodness of fit since it does not automatically increase as independent variables are added to the model.
AIC is preferred if the purpose is prediction, BIC is preferred if goodness of fit is the goal, and lower values of both measures are better.
djusted R2侧重的是调整后的拟合,AIC和BIC是没有调整的模型,然后AIC是侧重模型的预测能力。
