- 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.
