- FitPoly( <List of Points>, <Degree of Polynomial> )
- Calculates the regression polynomial of degree n.
- Example:
FitPoly({(-1, -1), (0, 1), (1, 1), (2, 5)}, 3)yields f(x) = x3 - 1 x2 + 1.
- FitPoly( <Freehand Function>, <Degree of Polynomial> )
- Calculates the regression polynomial of degree n for a function drawn by the Freehand Shape Tool.
CAS Syntax
- FitPoly( <List of Points>, <Degree of Polynomial> )
- Calculates the regression polynomial of degree n.
- Example:
FitPoly({(-1, -1), (0, 1), (1, 1), (2, 5)}, 3)yields x3 - x2 + 1.
Note:
- For order n there must be at least n + 1 Points in the list.
- See also FitExp Command, FitLog Command, FitPow Command and FitSin Command.
- If you work with big/small numbers, you should consider normalizing them for a more accurate result, see Normalize Command.
