字符型转换成数值型的STATA方法 字符型转换成数值型的STATA⽅法 1、encode varname, gen (newvarname)，重新⽣成⼀个新的变量，内容与字符型的相同。2、 Convert string variables to numeric variables：destring [varlist] , {generate(newvarlist)|replace} [destring_options]字符转数值 Convert numeric ...
请看看Stata对encode的说明:encode creates a new variable named newvar based on the string variable varname, creating, adding to, or just using (as necessary) the value label newvar or, if specified, name. Do not use encode if varname contains numbers that merely happen to be stored as s...
