   How many lines?

   It,s like a few lines using linear algebra library. All you're doing is solving a linear system.

   Depends, if I reg x y or reg y x

   And about 200 more to load the data...

   Model m = new Model(t=“Linear”, vce =“robust”);
   Result r = new Result();
   r = m(y,X);

   Yes, I know, but Barton & Nackman take 60 pages to explain an array, so I guess this is complex

   If this is true, is not too bad

   BS. This is not valid C++ code.

   I spend one month to run regression proper with pen and paper

    He also conveniently omitted the part where the matrices y and X are formed.

    which line is not valid?

    It may be syntactically correct but it is not, by far, a complete program. The trouble with C++ is that there is no support for "natural" array operations. Forming the y and X inputs above will be a complete pain relative to the same operation in Stata or even Python. Even the Boost project, which is huge, does not provide a means of reading CSV or Excel files.

    man you guys are such amateurs. You need to load your data into a matrix object as defined by your C++ matrix library. The library itself probably has a way of loading a csv file.

    You're better off using R anyways. It's designed for this kind of work.

    don't waste your time on r or python, use stata and publish well

    Every time before I run a regression, I first recap three semesters of measure theory.

    Covariates are separated with "+", not "," in R.
