- RSquare( <List of Points>, <Function> )
- Calculates the coefficient of determination
*R² = 1 - SSE / Syy*, between the*y*-values of the points in the list and the function values of the*x*-values in the list. **Example:**`RSquare({(-3, 2), (-2, 1), (-1, 3), (0, 4), (1, 2), (2, 4), (3, 3), (4, 5), (6, 4)}, 0.5x + 2.5)`

yields*0.28*.
