Dear all, Could you please help me with my confusion on unit root critical values? The fact that the ADF t-stat is smaller than the critical value at 5% indicates rejection of the null but what about the critical value at 1% level of significance? In the case below it indicates that null cannot be ...

I believe that 100% of EViews/R users who have posted here on the topic occasionally need to save in both ways. :)

With other formats with multiple options (e.g. Excel) you have more than one choice in the drop-down. Wouldn't be hard to have two RData choices there.

Makes sense, but it would be nice to also have the option on the Save dialog.

Sometime (in the last year I think), there has been a change in how .RData is saved. Series used to be saved as time series. Now they are saved as numbers with the dates put in as row names. While I think this was a good change, it would be nice to have the option of saving in the older format as we...

You have perfect multicollinearity.

Right, the coefficient will be beta1 + beta2*z

Is


what you want?

One possibility is that in the original specification there was a lot of missing data for the right hand side variables, eliminating all the 1's.

Why does the linewidth change when I freeze a graph view? Is that intentional?

Take a look at the attached workfile and do a simple View/Graph of inflation. The default limits seem to be nuts. I think this is because I had a previous definition of inflation which produced different limits and this has somehow stuck.

For the first-stage F you want the reduced form. Wouldn't you get the same generalised equation but like different letters instead? How would you do it with so many variables? What difference does it make? Cause I did get an answer but I think I did it the structural formula way and get a low F-sta...

That looks correct. So it's probably a problem with your data. Could it not be something to do with the second equation having 1 additional variable compared to equation 1 or that the variable X2 exists in both equations? Nope. The former means that the first equation is overidentified and the latt...
