    Hello sir, watching from India, your enthusiasm to teach new people and shape the new generation is really commendable. Thank you so much for your efforts. I found this channel from your video on World Bank open datasets. I would like to request you if you can use AI like Mister Beast and translate your upcoming videos into Hindi. I mean to say that UA-cam has that option by which you can share your video with dual audio, so you can cater to your English audience as well, and we Indians can learn from a great teacher like you. Even if it is not possible, we will watch your videos by turning on the subtitles. A big thank you. 🙏

  • @이기찬-w5e

    I have some specific questions: (1) If the Hausman test favors the RE model over the FE model, can I still proceed with using the FE model? (It is because in the management field, considering that FE is more prevalent in research papers.) Is the Hausman test an absolute criterion? (2) I am using a two-way model with i.time and i.industry. Can both FE and RE models be applied in this case, or is only FE suitable? (3) In one of your UA-cam videos, you mentioned that when time-invariant variables (e.g., gender) are included, the RE model [(cov(z_i, u_i) ≠ 0)] instead of FE model [(cov(z_i, u_i) = 0)] is more likely to be preferred. In my case, the independent variables consist of "diversity" measured by gender, age, and education level. As age is a time-variant variable, would it still be appropriate to favor the RE model? (4) The secondary panel data includes industry classifications with 2-digit and 3-digit numbers. When conducting research with industry as a factor, is there a preference for using 2-digit or 3-digit numbers? Or is it at the discretion of the researcher? (It is because there is limited specific explanation in previous studies). I have reached out to the authors, but they used different industry numbers in each case. Thank you. I am looking forward your response for my question. Sincerely, James

      It really shouldn't be any different. Just treat each column (wide form) as a "time period." It doesn't matter if its annual or quarterly or daily even.

      Hmmm, you may be able to use multiple stubs? I can try this later to see. Otherwise I may just extract into separate data sets. I’m sure there is a more efficient way, but when in doubt I just divide and conquer!

      try: reshape wide var, i(panelvar) j(timevar) OR you can also just use a collapse command to get average for years. Be sure to save data set first though, as collapse changes it. collapse (mean) varname, by(timevar)
