### Re: PEDRONI COINTEGRATION TEST

While I'd have to look at the data to be certain that I understand what is going on in your particular case, you should note that most of the Pedroni statistics follow a normal distribution and diverge to negative infinity under the alternative hypothesis (Pedroni, 1999, "Critical Values for Co...

The default is whatever is in the corresponding coefficient vector when you begin the estimation procedure.

### Re: a program to calculate predictive probabilities

Make a model object from your estimated equation using Proc/Make Model (or the command equivalent). This will give you a set of equations each of which corresponds to the category probabilities. Simply solve the model to evaluate at the observed data for a given sample, or use the tools in the model...

### Re: Different results with EViews5 and STATA

While your point about there being perhaps unsurprising differences in implementation is certainly true, I do want to note that In the program Stata Levin-Lin program in question is not an official Stata routine with all of the vetting that that entails, but rather one written by users for their par...

### Re: Principal Components Analysis

Possibly the best way for you is to, instead of storing everything onto disk in your loop, put your results in a spool object. Then you can look at individual results in EViews. You'll have to look at the docs for a discussion of how to do this...

### Re: Different results with EViews5 and STATA

I've spent a bit of time looking into the differences between the Stata/ levinlin and EViews results and have some answers. The following discussion refers to both EViews 5.1 and EViews 6, in comparison with the 1.1.5 version of the levinlin ado. There are four reasons for differences between the le...

I'm afraid that I don't quite understand what it is you are trying to do. What exactly do you mean by displaying the results one by one?

### Re: Different results with EViews5 and STATA

Most probably a d.f. correction issue. Can you send your workfile to support@eviews.com.

We might not get a chance to look at it until next week as there are quite a few things going on right now, but we'll see if we can take a look.

### Re: Extreme Value Theory

The first part of this request is somewhat broad and difficult to answer. EViews does not have tools designed specifically for perform extreme value theory analysis, but does have tools that are relevant. Extreme value theory is not something I've had a lot of experience with, but my brief look at a...

### Re: Different results with EViews5 and STATA

Not being familiar with the Stata Levinlin package I can't say for certain, but given the relative simplicity of Levin-Lin-Chu, I would guess that it has to do with differences in degree-of-freedom corrections for the variances used in the ADFs. This isn't a theoretical difference, but rather a prac...

### Re: Ordered probit model

FIrst off, what version of EViews are you using and what's the build-date (Help/About EViews)? I know that we've made some improvements in the automatic determination of starting values in recent versions of EViews that may help. Apart from that, there is an option in estimation to use the starting ...

### Re: Create series for multinomial logit

Another method:

Code: Select all

`x.classify(method=limits, rightclosed) 0 2.5 7.5 @ y`

The one issue here is that the encoding will start from 1 instead of 0. You can, using the same proc, define value maps for the encoding which will be attached to the resulting series.

Just to clarify. The book to which the poster is referring is the "EViews Illustrated" book by Richard Startz, not the EViews 6 manuals themselves. That said, the data should be in the EViews6 installation folder in a folder named "EViews Illustrated Data," if, on installation of...

There's an option when you run programs to continue even if you get errors up to a maximum number...It's set at 1 by default, make it bigger.
