Do文件编辑器的改进(Do-file Editor improvements)。随着编程的重要性日益提高,Stata 16在Do文件编辑器中加入了 “自动填写完成”(autocompletion)与 “语法高亮”(syntax highlighting)的功能。Stata 17又将Do文件编辑器的功能进一步提升。 在Stata 17的Do文件编辑器中,可通过设置 “bookmarks”(书签)而在一个较长...
replace var1 = mean(var1) if missing(var1)如果我们要对多个变量进行处理，可以借助 egen 命令，例如：egen var2 = mean(var2) if missing(var2)在进行数据清洗时，我们还需要注意重复值的处理。例如，一个人可能参加了多次调查，如果我们不进行去重处理，可能会导致数据分析结果出现偏差。我们可以使用 sort ...
功能方面。Stata 的绘图功能主要通过绘图语法(Syntax)及其绘图编辑器(Graph Editor)得以实现。其中,Stata 的绘图语法以 graph 命令开头,包括绘制各类图形的绘图命令(graph commands)以及图形画好后用来删除、读取或多图合并的绘图管理命令(graph management commands)。下表简要列举了两类命令。 绘图命令(graph commands) ...
More convenient syntax for generate generate . generate a = 2 + 3 or . generate b = "this" + "that" without specifying whether new variablebis numeric or a string of a particular length. If you wish, you can also type . generate str b = "this" + "that" ...
Sort works by sorting by the variable specified first, then moving on to the second variable, and so on. In Stata, the command uses the syntax ‘sort varlist’, where varlist is a list of variables. Sort is useful when one wants to examine the data within an individual variable, or ...
