Bring them all into one page, then structure by those two series

### Re: Coputation of fitted values

Again, without knowing exactly what you're doing, there's no way for us to help.

To start, if I were you, I'd take a look at what the code I posted does, take a look at what you're doing, and then compare to see how they differ.

### Re: Coputation of fitted values

Thinking about it a bit, yes your code will compute it correctly too.

You can confirm this by adding this code to the bottom of my code:

Code: Select all

`select.makeresid ordinaryselect.makeresid(g) generalselect.fit yprobseries imills2 = general*(1-yprob)/ordinaryshow imills2 imills`

### Re: Coputation of fitted values

Heckman selection is widely used - but aren't most estimated with the superior ML method rather than 2Step?

I'm not sure if your calculation is correct, but I'm pretty sure the one in the code I posted is, and matches the wikipedia definition of the ratio.

### Re: Coputation of fitted values

It was our view that the literature had moved away from the two-step model, and only included it for completeness. There's really no reason to estimate using the two-step method other than as a teaching tool (same argument as two-stage least squares). Having said that - no idea why your estimation i...

Without going into the econometrics, the equation is estimated in differences.

### Re: Coputation of fitted values

Somewhat obvious question - but when using the built in method of estimation, did you use two-step or ML?

### Re: Adding ability to read Oxford Economics databases

Oxford (or anyone else) would need to write an EViews database extension to allow EViews to read their data. We no longer write extensions for non-free data sources, but since it is an open language anyone can write their own.

### Re: Midas Intra-period forecast

EViews will forecast from a MIDAS equation using the straight forward calculation of the specification. That specification may include both lags and leads of the higher-frequency variable. To get the "weekly updated forecasts" you might have to re-specify the equation's leads/lags.

RESID has no data. Are you sure you want it to depend on RESID?
