没有人。。大神们呢。。呜呜

mkmat x*, mat(X)
mkmat y, mat(Y)
mat S=inv(X)*Y
svmat S

不是很懂。。可以解释一下吗？stata入门都不算。。

put you data into stata with 6 variables and 5 observations, the variables are x1 x2 x3 x4 x5 and y, we then put x1 x2 x3 x4 x5 into matrix X by using "mkmat x*, mat(X)" and put y into matrix Y, then solve the matrix equation using mat S=inv(X)*Y (in algebra, we can think the solution is as XS=Y, so S=X^(-1)*Y), "svmat S" put the solution back in the data with variable name S1

讲的好细致，英文的解释我都看懂了，谢谢您了
虽然原理我不清楚，但是以后至少可以代入公式了，再次谢谢了
