Outlier detection

[Weaver102406]

I am attempting to detect outliers for my data, but I do not see the 'Stability Diagnostics' option when I click on View. What do I need to do? Also, once I am able to execute the leverage plots and influence statistics, what metric do I use to determine an observation is an outlier?

Thanks,
Carol

Stability Diagnostics is only available for equations (and only for certain estimation methods), and in EViews 7. If you don't see it, and you're using EViews 7, it is probably the case that you're not looking at an equation object.

I am using Eviews 7 and estimated a least squares equation..both ordinary and with random effects, but do not find the Stability Diagnostics option. I have used it in the past and am not sure what I am doing wrong today. :)

Thanks!

It isn't available for panels.

What method would you suggest for detecting outliers in panel data since these are not available?

[EViews Glenn]

Part of the reason it is not supported is that once you get to panel data the concept of an outlier becomes more vague. We are not particularly comfortable advocating an outlier method in this case.

Thanks...I'll check with my professor for his recommendations.
