Hello!

I am doing Fixed Effects and Pooled OLS regressions using panel data in EViews 7. In the regression output (7th row) I have: Total panel(unbalanced) observations: 414.
I would like to ask you: why is there "unbalanced", when if I structured my data as Dated panel? Also, why is there only 414 observations, should not there be 42 countries, 13 time period, 12 explanatory variables => (42*13*12) – 151(missing data) = 6401 observations?

Many thanks!

Some (many, by the sounds of it) observations have missing data.

yeah, 151 observations have missing data, but why it is written 414 observations, if I should have 6401? (42countries*13years*12variables).

Any idea, why it says total panel(unbalanced) in the regression output, even if my data is structured as Panel Data and thefore should be balanced?

More than 151 observations have missing data.

how can you know? exacly 151 observations have missing data.

and what I would like to also ask you why does it say total panel(unbalanced) in the regression output, even if my data is structured as Panel Data and thefore should be balanced?? - (it is the 7th row in the regression output)

Well without providing the data, I can only go by the scant clues you've given. But the fact that EViews dropped so many observations indicates that many observations had missing data.

It is unbalanced because cross-sections have missing values at different observations.

I am sending my data as attachement

Provide the EViews workfile, with the equation.

sending as an attachment

The workfile has 546 observations total. The equation uses 414 of them. So 132 are dropped. They are dropped unevenly from different cross-sections, hence the unbalanced nature of the estimation.

Note that observations are counted as rows of data, not individual data values.

ok. thanks.

Does the unbalanced nature effect in any way the results?

No.

ok, thanks for your help!
