The homoskedasticity - only F - statistic is given by the following formula A. F = (R^2 _unrestricted - R^2 _restricted)/q/(1 - R^2 _unrestricted)/(n - k_unrestricted - 1)
B. F = (R^2 _unrestricted - R^2 _restricted)/q/(1 - R^2 _unrestricted)/(n - k_restricted - 1)
C. F = 1 - R^2 _unrestricted)/q/R^2 _unrestricted/(n - k_unrestricted - 1)
D. F = (R^2 _unrestricted - R^2 _unrestricted)/q/(1 - R^2 _unrestricted)/(n - k_restricted - 1)
