模型拟合: 查看模型结果:其中residuals是残差,就是实际值与理论模拟值的误差,intercept是截距,后面的pr(>|t|)是p值,越小越拒绝原假设,结果越显著,还有adjusted R-squared表示模型拟合优度,越大越好.fitted即是通过模型拟合出的理论值. 模型可视化: 拓展: 当自变量为多个时,这时未满需要拟合出一个函数,将y用几...

Rd方案是不符合移植条件的NDMM患者的有效治疗方案[2]。药物毒性是健康水平中等和虚弱患者在治疗时需要主要考虑的问题,因为这类患者出现AEs从而导致治疗中断的风险较高[1]。健康水平中等的患者的治疗目标应当是在保持生活质量的前提下获得...

R-Squared vs. Adjusted R-Squared R-squared only works as intended in a simple linear regression model with one explanatory variable. With a multiple regression made up of several independent variables, the R-squared must be adjusted. Theadjusted R-squaredcompares the descriptive power of regression...
