index=st_addvar("long",("X1","X2","X3")) st_addobs(rows(Y)) st_store((1,rows(Y)),index,Y) 其中st_addobs(rows(Y))的作用是将Stata数据中的obs设定为这个矩阵的行数。缺少这一步,Stata可能会报告出错。 输出矩阵就容易多了,st_matrix("r(A)",A)将矩阵输出到r(A)中,st_matrix("e(...

日常开发中,我们使用到的Js定义的每一个值都属于某一种数据类型,常见的js数据类型有String(字符串)、Number(数字)、Boolean(布尔)、Object、Undefined、Null、Symbol等等,其中Symbol是ES6引入的新的数据类型,表示独一无二的数值。因为 JS 本身是一门弱类型语言,
Strings can be programmatically loaded from multiple data file types usingloadd. No special steps are required, and GAUSS automatically detects strings in XLSX, CSV, STATA, SAS, and GDAT files. In addition, theData Importwindow provides a great tool forinteractively previewing and managing dataof...
