When working with data, it is often necessary to calculate composite indicators that summarize multiple variables into a single measure. This can be done using assignment statements in Stata. To create a composite indicator, you first need to decide which variables you want to include and how you...
New data-management features misstable summarizewill now create summary variables recording the missing-values pattern via the newgenerate()option. Back to highlights SeeNew in Stata 18to learn about what was added in Stata 18.
Stata's tables for epidemiologists make it easy to summarize your data and compute statistics such as incidence-rate ratios, incidence-rate differences, risk ratios, risk differences, odds ratios, and attributable fractions. You can analyze stratified data too—compute Mantel–Haenszel combined ...
所谓“留一元分析”,就是在进行元分析时,每次均留出一个研究(即omitted study,不放在样本中),以考察元分析结果的稳健性;比如,ZUI终结果是否过度依赖于某个研究。在使用Stata命令meta summarize或meta forestplot进行元分析时,可使用新增的选择项leaveoneout来进行留一元分析。
To summarize: if α is too small: slow convergence. if α is too large: may not decrease on every iteration and thus may not converge. 特征和多项式回归(Features and Polynomial Regression) 之前我们介绍了多变量的线性回归,现在我们来学习一下多项式回归,其能帮助我们使用线性回归的方法来拟合非常复杂的...
