Which of the following correctly represents the equation for adjusted R²? A) = 1 - [SSR/(n -1)]/[SST/(n+1)] B) = 1 - [SSR/(n -k - 1)]/[SST/(n+1)] C) = 1 - [SSR/(n -k - 1)]/[SST/(n - 1)] D) = 1 - [SSR]/[SST/(n - 1)]

The adjusted R-squared formula is as follows: 
1 - [SSR/(n - k - 1)]/[SST/(n - 1)], where SSR is the sum of squared residuals, SST is the total sum of squares, n is the sample size, and k is the number of independent variables in the model. The given equation includes all necessary elements and matches this formula, making choice C the correct answer.
