Yes, that was the problem and I just saw that I had renamed the variable. But I still have a problem, for some other variables I still can't apply the test, and I'm getting this error message:
near singular matrix error. Regressors may be perfectly collinear in equation "temp.ls dy y(-1) c @trend(@trend>13-2) )@trend>13-2)*(@trend-13+2) dy(-1to-3)

I've already tryed changing the model, changing the maxlag, and changing the Trimming parameter. Nothing works...

I am new user of Eviews and I have to apply Zivot-Andews Unit root test on my data on both level and first difference. I have applied your code and it is working quite well but it is only showing one value of t-states and prob. I am little bit confused that either this values are for "level" or for "first difference". Please guide how i can obtained both values of Level and first difference by using your provided code.

I am looking for prompt response from experts. Thank you in advance.

Hello Everyone!
Can anybody help me in applying these codes?
I don't know how to apply these codes because these codes are not working for me at all.
I have tried everything.

Thank You
