How is RData saved

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

Re: Dependent variable has no variance - Logit regression

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.

line width changes when freezing?

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

graph axis limits

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.

Re: 2sls with 2 simultaneous equations

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...

Re: 2sls with 2 simultaneous equations

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...

Show us the commands you use and maybe attach the EViews workfile. Quick, Estimate Equation, 2sls Equation specification: Y1 c Y2 + AX1 + BX2 + CX3 + E Instruments: AXI BX2 CX3 DX4 FX5 GX6 I think I got near a singular matrix for this one.

Re: Saving data in R

But it would be good if the documentation said that dates are pushed out a row names. And while I am whining about documentation... (1) if you type R into the online search you get told (no results) (2) when you get yourself to http://www.eviews.com/help/helpintro.html#page/content%2Fexternal-EViews...

Re: Saving data in R

That's very helpful. It's a little weird though that if you SaveAs and choose Excel you get a dialog to choose series but you don't get that dialog if you choose R. Maybe some part of your response Steve could make its way into the documentation, which is a bit sparse on what gets passed to R under ...
