      you said if prob is less than 5 % then it is non stationary but when interpreting you said that FDI is stationary at level and 1 difference but in 1 difference prob is not bigger than 5%.

    • @QRSchool

      This is called mix level of integration. At first difference, at both trend and trend & intercept, the trend should not be there.

      Wonderful presentation!!!
      But pls kindly review your statement regarding the stationarity of the FDI data series with Prob = 0.072 which is greater than 0.05 (5%).
      Whereas Ho: Data series are non-stationary.
      Whereas also, decision rule states: reject Ho if Prob ≤ 5%(0.05)
      Pls, how then did you conclude that FDI is stationary?

      If the dependent variable is dichotomous, logistic regression can be applied. For example: Gender is dependent variable, which has normally two options (Male & Female), it makes it dichotomous variable.

    • @QRSchool
      @QRSchool  4 роки тому

      For regression, it is important that data series of variables should be stationary. We can change the measurement of the data. Even then, it is non-stationary then in this case regression is not appropriate.
