R² is the formula for calculating the coefficient of determination (R-squared) in regression analysis. R-squared measures the proportion of the variance in the dependent variable that is explained by the independent variable(s). The formula for R-squared is: R-squared = 1 - (residual sum of squares / total sum of squares) Therefore, the correct answer is C, which matches the R-squared formula.
