Could you please help me to calculate F-statistic for 2SLS.

It is reported that: The summary statistics reported at the bottom of the table are computed using the formulae outlined in "Summary Statistics".

I’m trying to calculate F-statistic as

F = R2*(T-k) / (1-R2)*(k-1)

For instance:

R-squared = 0.91555469

T = 43 (observations)

k = 3 (2 explanatory variables and intercept)

Instrument specification: 2 instruments, Constant added to instrument list

According to this formula F = 216.8397

Eviews returns F = 229.4930

How should I change expression to get Eviews value?

I can not find something about it in literature.

Thanks in advance.
