- FitPow( <List of Points> )
- Calculates the regression curve in the form a xb.
- Example:
FitPow({(1, 1), (3, 2), (7, 4)})
creates the regression curve f(x) = 0.97 x0.71.
CAS Syntax
- FitPow( <List of Points> )
- Calculates the regression curve in the form a xb.
- Example:
FitPow({(1, 1), (3, 2), (7, 4)})
yields 0.97 x0.71.
Note:
- All points used need to be in the first quadrant of the coordinate system.
- See also FitExp Command, FitLog Command, FitPoly Command, and FitSin Command.
- If you work with big/small numbers, you should consider normalizing them for a more accurate result, see Normalize Command.
