    Hello Professor Bob, first of all, thank you very much for the video, that question came to me in my evaluation of the econometrics I course and at the time I had no idea how to develop it, I am from Peru. Just one question, I look at the A-66 but it is not very clear to me how it replaces it, refer to xs term in the expression, please if explain this part. Greetings.

    You are a very good teacher, Bob Wen. I failed to follow ALL THE OTHER videos because the speakers were too fast (who speaks so quickly, teaching? How can one learn? The y have to put themselves in the learner's shoes.) But you, Bob, are so good. Keep it up!!!!

    Thank you for your teaching videos. They are very helpful. I was wondering if you have a video on how to combined more than one observations into one single observation in stata. To be clear, let us assume this scenario on disability types: 1- Difficulty in seeing : Yes = 1, No = 0 2- Difficulty in walking : Yes = 1, No = 0 3- Difficulty in speaking: Yes = 1, No = 0 4- Difficulty in hearing : Yes = 1, No = 0 Then we want to combine all these 4 observations into one single observation. This single observation can be named Persons with disability ( Yes: 1, No:0), Any guidance will be appreciated.
