So it is much safer to use local macros, which never clash with anything outside their own do-file (or command-line window session). removes a value label association from variable whatever without destroying the value labels. The bugs that are caused when such name-clashes arise are extremely frustrating to find and fix. Variable labels or value labels I guess the second: Code: label val whatever. This is a real problem because you can't always know what other programs are running when you run your code. Global macros are subject to name clashes with global macros defined in other programs that are running. For instance, pretend that the order of the variables in the dataset is. type dates2.raw John Mary Kate Mark Jun/8 1959. For example, consider the file dates2.raw. Foreign: Read Data Stored by Minitab, S, Sas, Spss, Stata, Systat, Weka. When the names are in common, the variables are numbered sequentially, but they are not stored sequentially. The date () function is very flexible and can handle dates written in almost any manner. space rm(listls()) Remove all but some rm(listsetdiff(ls(),c(temdata. But let me add that the use of global macros for this purpose is unwise. The only thing Stata is missing is an easy way to specify variables v1, v2.

(And put it between code delimiters - see FAQ #12 for instructions - so it always comes out easily readable.) You should always show the exact code you actually ran, by copy/pasting from your do-file or the Results window into the Forum editor. Little details that the human eye misses are often crucial. But one thing you shouldn't do here is type your code directly into the forum. This is unlike global macros which continue to exist in Stata’s memory when they are run the first time.

When run together, Stata will display an output of 10.

I assume this is a typographical error you made in posting, because if you actually ran that command you would have gotten an error message right there. In order to display an answer of 10, we have to select both of these commands and execute them together. The error message you are getting is not particularly informative: the problem isn't really about unmatched parentheses or brackets, it's about undefined macros.Īs an aside, in your second try, your first command begins with -glolbal-, which is a non-existent command. Similarly, in -biprobit ($d1 = $w1) ($d2 = $z1)-, both global macros w1 and z1 are non-existent. When you write -biprobit (y1 = $w1) (y2 = $z)-, you are referencing a global macro w1 that does not exist. The method can be used to remove cluster confounding due to observed confounders by.
