i have some problems with formulas.
The first formula that i found in the internet
The second formula
I calculate R-Squared Adjusted through stats.model in Python and thats it equal 0.610408.
R-Squared ≈ 0.6415759298804311
n = 51
k = 4
First formula result = 1 – (1 – 0.64157) * (50 / 47) ≈ 0.61869
Second formula result = 1 – (1 – 0.64157) * (50 / 46) ≈ 0.610408
Why is the first formula that is on the internet incorrect?
