StataLogistic regressionBinomialDespite the widespread interest in meta-analysis of proportions, its rationale, certain theoretical and methodological concepts are poorly understood. The generalized linear models framework is well-established and provides a natural and optimal model for ...
AuthorBill Sribney, StataCorp Yes, commands used with thesvyprefix treat zero weights differently than commands that allowpweights used without thesvyprefix. Thesvyprefix dots all the i’s and cross all the t’s—meaning it gets all the details right for complex survey data. Although one ca...

数组在进行批量操作不必进行for循环,称这种特性为向量化 基础索引与切片 一位数组的操作比较简单,看起来和列表类似。区别在于python的内建列表,数组的切片是原数组的视图,原地操作。所以如果只想对数组的copy切片,必须显示的复制数组(copy()函数)。 在二维数组中,每个索引对应的元素是一个一维数组 ...
With the introduction of Stata's margins command, it has become incredibly simple to estimate average marginal effects (i.e., "average partial effects") and marginal effects at representative cases. Indeed, in just a few lines of Stata code, regression results for almost any kind model can be...
Data were entered and analyzed using EpiData version 3.1 and STATA version 14. Descriptive statistics were employed to summarize the information. To investigate factors linked with outcome variables, bivariate and multivariate logistic regression analyses were conducted. The results ...

See A brief introduction to MI using Stata in [MI] intro substantive for details. The data we used are stored in mheart1s20.dta. Below we refit the logistic model using the imputed data. We also specify the dots option so that dots will be displayed as estimations are completed. . use...
