Correlation

[alim]

Hi everyone

I am facing new problem. I have two variables. At level the R square .95 and 1st difference they are stationary but when I check their relationship in 1st difference, it shows R square .01. If I estimate date with 1st difference, is it ok?. My second question which relationship is true.

If any one knows the answer, please write. It will help many people like me.

With regard
