EViews.com

my eviews version is 6.0.

and when I run the Fisher (combined Johnasen) test，it always shows me that message wrong and looks like that ：Invalid or duplicate specification or insufficient data for estimations，

but I don't know why. could you help me to handle this problem, thank you so much, it's my first post~~~ :D

Can you tell us the build date of your copy of EViews 6? You can find this out by clicking on Help->About EViews.

Jun 3 2008 build.

there are only two options in about Eviews, one is ok and the other is credits. I clicked both of them, but doesn't work.


thank you ~~

You should update your copy of EViews. That might fix the problem for you.

thank you so much, I will try~~
