Hi,

I imported a time series from Excel to Eviews, i took the first difference and when i tried to do an AR(1) model that message appear: illegal lag or index specification for coefficient c

I realized that all values at "c" are equal to zero. Is that a problem right?

What can I do?

I wrote ar1 = employement c ar(1) , where employment is my time serie.

Help me please!!

That's not the command do a regression. You might want to look at the examples in the manuals, tutorials, or EViews Illustrated.
