t检验(t-tests):匹配后各协变量的t检验结果应不显著(即p值大于0.05),表明处理组和对照组在这些协变量上没有显著差异。 图示(Graphs):匹配前后的协变量分布图(如直方图或密度图)应显示处理组和对照组的协变量分布更加接近。 Mean:处理组和对照组在匹配后和匹配前的均值差异(标准化差异)。 %Reduct:匹配后标准化...
如何使用codebook、summarize命令了解某一个变量x的缺失值、统计量,并使用stem、graph box、histogram命令画出茎叶图、箱式图以及柱状图; 如何使用twoway graphs来展示数值型变量x和y之间的关系,并画出散点图(scatter plot)、折线图(line plot)、带数据标记的直线图(connected plot)等多种图像; 如何使图像变得更加美...

Watch Transparency in Stata graphs. Watch Modifying sizes of elements in graphs. Regression fit graphs Added-variable plots (partial-regression leverage plots) Component-plus-residual plots (partial residual plots) Augmented component-plus-residual plots (augmented partial-residual plots) Leverage-versus...
Stata allows you to adjust the transparency of elements in graphs it produces. By default, elements are not transparent. That means that graphical elements on top of each other obscure each other. By changing the transparency, you can see what lies underneath, and that usually produces better-...
在菜单栏中选择Statistics > Survival analysis > Graphs > Survivor and cumulative hazard functions,我们可以选择生存曲线(Function选项中Graph Kaplan-Meier survivor function) 或死亡曲线(Function选项中Graph Kaplan-Meier failure function),并且可以在下...
