- FitPoly[ <List of Points>, <Degree n of Polynomial> ]
- Calculates the regression polynomial of degree n.
- Example:
FitPoly[{(-1, -1), (0, 1), (1, 1), (2, 5)}, 3]gives x3 - x2 + 1.
Note:
For order n there must be at least n + 1 Points in the list.
Note:
See also FitExp Command, FitLog Command, FitPow Command and FitSin Command.
