分别键入上述每个命令是一项繁琐的任务。相反,我们可以使用 Stata 中提供的loops选项,并使用 foreach 命令,如下所示 foreach var of varlist pcgdp gdpgr eduexp govtexp netoda { gen `var'_log = ln(1+`var') } 注意: 左括号{与 foreach 出现在同一行 Stata 命令(即 gen...)出现在新行上 右括号...
Stata interprets "< 3" as a variable name. Any suggestions for loops and if statements using delimiters would be greatly appreciated. * * For searches and help try: *http://www.stata.com/help.cgi?search*http://www.stata.com/support/faqs/resources/statalist-faq/*http://www.ats.ucla.ed...

} (On one computer the first loop consumes 50%, i.e. the total that Statacan use on my Dual Core processor; on a different computer it takes"only" 30-ish percent. But on both systems there's a sharp drop toessentially nothing in the second loop. Any ideas why? An aside on why I...

Using macros and loops makes it quite easy. The first step is to create a macro with no entries. I created a global macro named “dichot”. Next I started my loop with the foreach command, telling Stata to look one by one at all of the variables in the data set. I tell Stata to...

[44]. Combining inconsistent evidence is inappropriate and may lead to a biased result—either an under- or overestimation of treatment effect. For closed loops within an NMA (i.e., both direct and indirect comparisons are possible; Fig.2), inconsistency assessment can be conducted. If both ...
We addressed this issue by positioning the needle valve directly on the bottom of the float tank, using compression fittings instead of hose barbs, switching from PVC to fluorocarbon tubing, and eliminating service loops in the tubing. Based on user feedback, we added a security cover to the ...
