Stepwise Ex1

[facilito]

Hi:

I'm new in Eviews and asking for the help with it. I have a problem with Eviews to which I can't seem to find the answer in the help files.
I want to estimate an equation like this:

flujo = -0.402 x X2- 0.239x X5- 0.209x X6 + 0.247x X11- 0.253x X12

In my workfile I got 23 different macroclimatic variables.

So I have the following Stepwise equation set up:

flujo C Xs

Now I want to run this regression but I got this message:

"Tolerances must be non negative"

Any help is greatly appreciated.

Hard to know what you're doing wrong without knowing exactly what you are doing.
