如果想不用i.运算,我们则需要通过tab gender, gen(gender_)把分类变量转换为一系列的哑变量,才能放入回归模型。所以正是i.运算,让Stata的回归建模变得简洁。 另外,如果使用i.运算符,那么Stata默认将第一个分组当成是对照组。当然,我们也可以指定对照组,通过ib运算或者char命令指定。比如要指定分类变量的第4个分类...

Stata’s official commands do not give much support to multiple response variables, although we gave an example earlier of the application oftabstat. One general strategy is to use anegenfunction to calculate something, (possibly)egen, tag()to tag just one observation in each of several groups...

As of Stata 16,bayesmhand itsbayesprefix commands support a new option,nchains(), for simulating multiple Markov chains. There is also a new convergence diagnostic command,bayesstats grubin. All Bayesian postestimation commands now support multiple chains. In this blog post, I show you how to...
