I don't know if this is the correct topic.

I have an unusual doubt, maybe a silly doubt. I am estimating a model with a dependent variable and four independent variable. I estimate with the metod Least Squares and I get the equation and the result of all the coefficients are 1. The r-square is also 1. It's a little weird, I think.

The data is ok. I don't know what i've done wrong. ¿What do you think?


Thank you four help.

Yes, you've done something wrong. But there's no way to tell what it is without a lot more information.

I'm thinking about what i've done wrong but I don't know. Maybe introducing the data, but i've just imported the data from a excel, and the data is from an official estatistic institute, copy-paste.

I've estimated with quick/estimate equation/dep variable c indep variable

Do you need something info else? I haven't done anything else..

Post your workfile.

Here it is

You're estimating an identity. PIB is actually equal to the sum of the independent variables. Thus the results are correct.

Yes, it's equal to the sum..So, the result of the coefficients are ok??Haven't I done anything wrong?The estimate is ok?

Without going into a lecture on econometrics, you cannot estimate an identity.

So, I can't estimate this model and I should choose another if I want to estimate a model...right?

Sorry, I'm not very good at econometrics

There is nothing to estimate with this model.

Ok!!! Thank you very much for everything!! You've helped me a lot!!!
