How is adjrsquare calculated?

Can anyone direct me to how the goodness of fit output 'adjrsquare' is calculated? I know it's the "Degree-of-freedom adjusted coefficient of determination" but can anyone direct me to literature on how it is physically calculated by the program. Thanks.

Hi Scott, it is

1-(1-Rsquare)*(number_of_observations-1)/degs_of_freedom

You can find the basic description here:
