在Stata中,if 函数通常与其他命令一起使用,以限制这些命令的作用范围。其基本语法如下: markdown command if condition 其中,command 是要执行的Stata命令,condition 是一个逻辑表达式,用于判断该条数据是否符合某一条件。如果符合条件,则执行该命令;否则,该命令对该条数据不起作用。 2. 如何在Stata的i
A common mistake is to use theifcommand as the argument. This is incorrect Stata syntax. Theifcommand was designed to be used with a single expression (often a local macro) inside programs and do-files. Using this command incorrectly results in the evaluation of the expression using only the...
keep in 1/100 ``` 上述命令将只保留数据集中的前100个观测值,其他观测值将被删除。 4. by条件命令 by条件命令是一种基于某个变量进行分组计算的命令。它允许用户按照某个变量的取值对数据进行分组,并在每个分组内进行特定的计算。by条件命令的基本语法是:by varlist: command,其中varlist是一个或多个变量名...
Subjectst: if command DateTue, 18 Jan 2005 11:13:24 -0500 Hello What is the best way to achieve the following in stata? I have a reasonably complex logical test and number of new variables to generate as a result of applying the test. Here is a minimal example. The real problem is...

If this is referring to Simulink and using the sim() command, see the CaptureErrors . Or perhaps it is the ReturnErrorsInInput you need; I am seeing information that is confusing about that. Example the simulation information for ExecutionInfo 0 Commenti Accedi per commentare.Più...
As this data will be transported into STATA I think that I should go for the SUMIF option. I am a bit unsure if STATA can read the Pivot Table. Do you by any chance know how I can summarise the EU- and non-EU emissions data by company? That is, a command saying sum emissions ...
in a command where you want that variable name (such as 'summarize' below). But if you want to examine the variable name and compare it to a string, you must treat the contents of local macro 1 as a string, that is, "`1'", which can be compared to a string "aRate". If the...
