    Can I use this diagnostic test (ARDL) on the panel data analysis ?

    Thank you very much sir.
    But my question here is how can someone correct the cusum analysis test when the lines graph is greater than 5% critical bound?.
    Thank you sir🙏

    For ARDL model testing for multicollinearity is not necessary , right?

    Sir whether we should mention probability value of F-statistic or observed r square value of diagnostic tests in our research paper ??

    Sir to correct the serial correlation u said take lag
    Lag of a specified variable u have taken whose variable is lag taken how lag is taken these are combined results u.e durbin watson value belongs to whole data so all variables lag is taken to correct error

    Sir for estimating ARDL is there a requirement of any minimum no of observations.I have used 28 yrs data.is this enough.

    1) How can I conduct a CUSUM & CUSUM SQUARE test using 10% Significance level?
    2) Are both essential? Or is it enough if my CUSUM Test is stable?

    • @obezipacademy
      @obezipacademy  Рік тому +1

      To conduct cusum test at 10 percent, right click where the 5% is displayed on the cusum result, then click on options, click where u see 5% Significance and edit to 10%, then click ok.
      Both are actually good to test, though cusum of square is further used to ascertain structural break dates in a model. Some scholars just report cusum without really conducting cusum of squares

      @@obezipacademy Thank you so much for your answer! Though both 5% & 10% significance CUSUM & CUSUM SQUARES plots are coming as the same (same magnitudes, same plots). I thought with 10% the band-width should have become wider.

      You have to report and interpret the results the exact way you go it. Explain the possible economic reasons why it's insignificant

      @@zoyashah7826 it simply means there is overconvergence. This means that the correction mechanism is oscillatory. in other words, the speed of adjustment fluctuates forward before settling to equilibrium. (note, the frequency of your data as well as outliers can play a role in this but by no means your ECM is wrong
