    I want to appreciate all my subscribers from across the globe (Africa, Asia, Europe, the Middle East, The Americas, and The Pacific). Thank you all for your support. I am encouraged by your comments, questions, likes and critiques. They keep me focussed and poised to do better. I will continue to contribute my little quota such that every student and researcher will independently analyse his/her data. My teaching approach is very practical. I adopt a do-as-I-do style. Many thanks to those who have supported me by telling others. Once again, CrunchEconometrix loves to teach, support my Channel with your subscription, likes, feedbacks and sharing my videos with your cohorts. Please do not keep me to yourself (lol) inform your friends, students and academic networks about my Channel. Tell them CrunchEconometrix breaks down the econometric jargons and teaches with simplicity. Follow me on Facebook, Twitter and Reddit. Love you all, greatly!!! 

    Thanks Dr. for sharing your knowledge. Quick question though. I am working with the natural log data of the NSE 20 Share Index. I have been able to estimate the GARCH(1,1) GARCH-M(1,1) and TGARCH(1,1) using the data. However, the EGARCH estimation is returning an error message "log of non-positive value". What could be the problem and how can I resolve it? TIA.

    • @CrunchEconometrix
      @CrunchEconometrix  Рік тому

      Hi Robert, it's possible that the EGARCH algorithm is unable to accommodate negative values. You may either drop the technique or change variables.

    • @robertndaiga5050
      @robertndaiga5050 Рік тому

      I changed the mean equation specification to return ar(1) ma(1). Would the equation affect the results or would it result in EGARCH(1,1) estimates?

    • @CrunchEconometrix
